Something is wrong with the kernel. As soon as I turn off the display it doesn't turn on again and I have to reboot. Does not happen with slim stock kernel.

Had to do with undervolting. Is there a default uv? If I set the same values I use in franco, I always get sod.
I never touched the voltages, neither franco: https://github.com/StefanescuCristi.../nightlies/arch/arm/mach-msm/acpuclock-8974.c
Check the test folders from the first post. I think I solved your sound problem.
Also, there's a nice surprise in there if you guys want to test. Look after mpd.

V26 is a success. Volume levels regained. Great job! I'm liking the speediness of the kernel.
Well, it's sunday and I'm releasing V26 for using it in the next week.
V26 - b61c5f53fde9123a4ee1f4084d34a8b21ffc2f9b
Kernel changes
TL;DR: updates for blu_active governor, audio_policy (for CM version only), fixed the "can't change the volume" bug. It's nothing huge, just small bug fixes and improvements here and there.
Ramdisk:
TL;DR: sync-ed the CPU governor tunables with CM, also tuned the cpu-boost driver with CM.
I'm working on a version with qualcomm mpdecision enabled (instead of in-kernel hotplug managing) and the governor from oneplus one (it's "interactive" rebranded as "bacon"). I've been running this version for the last 36 hours and I like how the phone feels. MPD isn't as bad as you think if you have a nice and smart governor. I think I'll release a stable version from mpd branch with the normal version of V27. If you want to test a beta-stable version of mpd, you can check the test folders for mpd-v26. The last commit on which that version was built is 141bb827b4684b0cfb9ab07d7ccfca7d44f5c422 (https://github.com/StefanescuCristian/hammerhead/commits/nightlies-mpd)

V27 - e2109d301cd4f53c1dbb59eaa49c384e3f942861
Kernel:
TL;DR: Linux 3.4.104, updates for the config file, blu_active governor, made ROW default IO sched (you can still change to BFQ, but I feel like app opening are faster with ROW), added the interactive gov from OnePlus One, the gov is called "bacon" (not active, you can set it in Synapse)
Ramdisk:
TL;DR: set inputboost to 1.3GHz, for 80ms, set vfs cache pressure to Linux's default.
Now, the interesting/new part
Kernel with qualcomm's MPDecison: V27 - d79badeb42d430b2bd76bfe062fb7f727be5a05a
Changes: I branched this from V25/V26, so it has all the things we have in V26 and pre-V26 plus:
TL;DR: Treat it as standard V27, but with bacon governor set as default, and mpdecision enabled. Also, with updates for rq_stats, the brain on which mpdecision takes decisions to online/offlne the CPUs.
MPD ramdisk:
Enjoy.

Since this is a hybrid kernel. Does it include the intellithermal from faux? Looks like an amazing kernel can't wait to try it
Uh for some reason I can't change anything in the intellithermal settings in synapse. Everytime I try to change thing it always revert back to default after I touch the apply button. What seems to go wrong?
Have you tried to reset Synapse?
I can change every single option in Synapse for intellithermal, except VDD restriction which gets set by the driver as far as I read/understand the code.
Edit: You probably know this and this is the reason you want to change the default settings, but I'll leave the link here. Faux recommended intellithermal settings.

I did reset the synapse. Reinstall and even clear the data but the result is just the same. Well I tend to keep my phone cold so that's why I want to change the temperature throttle a little more lower than that I hope you don't mind
. But I can't touch anything in the intellithermal settings without it reverting when I applied it.Edit: update it seems to work

The latest one, make sure you download the right version for your romwhich one to flash there are plenty of folders there

If it derps again and it doesn't work after reseting Synapse, go into a terminal and type uci reset; uciI did reset the synapse. Reinstall and even clear the data but the result is just the same.

I'm not responsable for data loss or any damage to your phone if you're using my kernel. You flash this at your own risk. Always make a backup!
(You need SuperSU 2.50 for this kernel to work!)
M/6.0 kernel:
Features:
- new name: almost-stock, since it's... almost stock, but not really.
- built on the base of latest Android 6.0 release, merged with franciscofranco's L kernel and CM/CAF12.1
- built with -mcpu=cortex-a15 for enabling maximum performance with our Krait CPU.
- reduced wireless wakelocks
- underclocked GPU idle (GPU min/max 20/450MHz)
- default CPU governor: CAF interactive, updated from CM/CAF12.1 branch.
- built with cpu-boost driver to handle touchboost, default touchboost is set to 500ms and 1.2GHz
- Motorola memory patches for ARM
- default hotplug: MPDecision with updated rq_stats from CM.
- I/O default schedueler: row
- the famous I2C @ 19.2MHz, plus some other chips dropped at 19.2MHz and voltages lowered for internal components (Cl3Kener)
- compilled with Linaro GCC (5.2.0) - arter's own build.
- removed useless debug
- workqueue udates from linux 3.7, power saving workqueues set on by default
- selinux enforced (You need SuperSU 2.50 for this to work!)
- partialsuspend enabled
- various updates and fixes for net, mmc, thermal, selinux, block, cpufreq, sched, rcu, block
- I probably forgot something

XDA:DevDB Information
[KERNEL] [6.0] almost-stock (aka ex big-bum), Kernel for the Google Nexus 5
Contributors
big_bum
Source Code: https://github.com/StefanescuCristian/hammerhead
Kernel Special Features: GCC5
Version Information
Status: No Longer Updated
Current Stable Version: 2
Stable Release Date: 2015-11-01
Created 2014-07-07
Last Updated 2015-11-0113This is it guys.
V8 is exactly what and how I want my daily usage kernel to be. I've added all that I've wanted in this version and I feel that there isn't much to add.
So this is it. The final/last/latest version of big-bum. The last doesn't mean the developement has stopped, it means that it slowed down, since there are any new features to add at the moment.
This being said, 1175 commits after V7, we have:
- Linux 3.4.106
- workqueue backports from @dorimanx, with a new tunable: power efficient workqueue (disabled by default). You can tune in Synapse or in /sys/module/workqueue/parameters/power_efficient
- cpufreq/cpuidle/sched updates and fixes from @neobuddy89
- crypto changes from CM
- ext4 updates
- dynamic fsync (just like in KK version)
- added the sound changes from CM/CAF
- wifi driver from Galaxy S5 , thanks to @myfluxi
- a new KCAL driver from @savoca (a bonus from me: a little bit of contrast and saturation added by default. Nothing intrusive, just a little boost to make our screen shine). Tune in /sys/devices/platform/kcal_ctrl.0/
- impulse governor from @neobuddy89 (great guy, thanks for all help)
- built with Linaro from Uber Kernel, toolchain is built from source.
- refreshed the build flags, and made them less aggressive
- I probably forgot something
Donations are not required, but are greatly appreciated.
I also started a caf kernel, since CM posted a caf tree yesterday night. I'm currently running Blisspop and I think they will switch soon to CAF, since CM will do that too. We'll see you there.12V23 - 9098f6e9afa9657eaf2b97cb89e535744afc030c

Most important changes:
Disabled arch power, sleepers and arm topology (UI is more responsive now)
added autosmp in kernel and fixed compile warnings, but not enabled
added msm_limiter, but not enabled. It limits the max freq, but in combination with autosmp third core was stuck at the maximum limit freq set.
added blu_active and blu_plug from Code Blue kernel, set as default.
added/replaced fastcharge with faux123's implementation. You can limit the voltage to 500mAh, 900mAh, 1200mAh, 1500mAh and 2000mAh. I don't recommend anything above 1200mAh, but hey, It's your phone.
Ramdisk changelog:

How to tune the two new beasts:
Universal Kernel Manager (Synapse + Script). Flash kernel, flash the zip from the link, install Synapse.9Reserved
Lollipop Kernel
Old kernel info:
9V7
From now on, I'll provide Linaro and SaberMod versions for this kernel.
USB stack is now at 3.4.105
FUSE/vfs/fat/fs fixes from 3.5, 3.6 and 3.7
qseecom updates from CM
f2fs updates from upstream
memory optimizations from motorola for our board are now merged with cortex ones
NET is 3.4.105
some video driver updates
selinux fixes
leds fixes
msm camera updates working as it should now
bluetooth is build at -O2 and I have reverted all the changes to stock kernel
enabled all frequencies for the CPU. Battery tests showed no (much) gain, but no loss either. @fabi_92 reported that the phone feels smoother, so it stays this way.
interactive: updates from CM/myfluxi
interactive: added a tunable in which you can choose the way the frequency is calculated (the old way, or the new load-based way). Writing 1 in /sys/devices/system/cpu/cpufreq/interactive/use_cpu_load will enable the new way of calculating the freq.
interactive: added a tunable to set the load threshold if you think the CPU doesn't stay enough in the minimum freq, but I recommend leaving it to 0 or not with it past 10-15.
added smartmax gov by request. It's not tuned and I don't offer support for it, so if you have crashes with it don't post them here.
underclocked GPU idle. The GPU runs at 20MHz now, instead of 27Mhz.
reduced wifi wakelocks
raised the thermal threshold frequency. It now goes down to 1.7GHz instead of 1.5Ghz, then if the cpu is still hot, it will the freq to 1.5GHz instead of 1.2GHz
Makefiles changes: merged some flags from Uber, added some parameters for our CPU, enabled hardfloat for NEON and VFP
mutex, rtmutex, semaphores updates
added tripndroid IO sched
I probably forgot something.
