Tiamat is a kernel designed for use on the Motorola Xoom. We are very exicted about the future of Honeycomb and Tegra development.
In compliance with the GPL, every change and all attributions can be found in full detail in my git repositories. Please feel free to explore, fork, or even cherry-pick (please include an attribution to the appropriate dev).
A progression in X indicates a major change or upgrade from previous versions.
A progression in Y indicates a stable release with some medium alteration or many small ones together.
A progression in Z indicates a minor change and is usually a testing release. Not all of these are released.

Removed the usb mass storage support. (being able to write directly to the external sdcard via your pc)
GPU automatic frequency scaling
ONLY SUPPORTS ANDROID 3.2
Apple Magic Mouse Support
1.7Ghz frequency tweaking
Cpu Frequency scaling patch - should be nicer now.
Disabled the autogroup scheduler
Voltage Controls - Thanks TDR!
Miscellaneous upstream changes
Introducing 1.7Ghz Overclock!
All frequency steps built in. 1.2, 1.408, 1.504, 1.6, and 1.7!
Two versions. Overclocked GPU and Stock GPU [request filled]
USB Tether work for real now! I personally tested with my Evo running Konikub's Evo Elite III Sense Froyo Rom. See below for script.
Added Realtek 8150 USB Ethernet Dongle Module [request filled]
Only get Official Tiamat Xoom Kernel releases from this location or download from Kernel Manager. As a user and Android Enthusiast, you can rest assured that the releases from these sources are SAFE. These releases have been rigorously tested and are suitable for public release.
As a Tiamat Xoom Kernel User, you agree to the following terms and common sense principals
As an Android Enthusiast, you are responsible for having a basic understanding of commonly used tools. These include, but are not limited to, ADB, shell, fastboot, and ClockworkMod Recovery.
You agree to follow the instructions EXACTLY AS POSTED. With recovery and Kernel Manager, it should now be relatively easy to flash.
You agree that this is a kernel development thread on a development website. You will treat other users with dignity respect. Your posts will be easily understandable and productive.
You agree to NEVER ASK FOR TIMEFRAMES OR ETA'S. I have a boss at work, and at home, and it's not you.
As an Android Developer, I pledge to release SAFE kernels that are as stable as possible. The goal of kernel development is to improve the performance, battery life, and provide additional functionality to Android devices.
I pledge to keep my Github repository up-to-date. You will ALWAYS be able to fork, pull request, or just review my source. In fact, I highly encourage user participation in the development process.
By clicking on the download links below, you agree to the terms and conditions set forth in the aforementioned paragraph.
General Overclocking Notes: 1.7Ghz is likely as far as we can push the Tegra2 cores. We have stress tested the heck out of 1.7 and it is safe. However, safe does not mean stable. Personally, I can run 1.7 on Interactive governor all day and it's smooth as butter. Other folks get reboots. If you can not run at 1.7, try 1.6. Everybody who tested was able to run at 1.504 without any problems. Just because this release is clocked to 1.7, that does not mean you can not run at stock speeds. Simply do not overclock. The settings for 1Ghz are identical to stock settings. I HIGHLY RECOMMEND you leave your device on INTERACTIVE. You may use Performance solely for benchmarking purposes, but then PUT IT BACK.
Woah... it's been a while since the last kernel release!
For this release, I have to give a huge shoutout to kcrudup, who was able to obtain the new modem drivers that are required for 4G to function.
Other than the 4G support, we have also added support for the lagfree cpu frequency governor.
Your first boot may take a while, depending on how many applications you have installed. Mine took about 8 minutes.
So here it is! The first kernel since the merge of Tiamat and Launchpad!
Firstly, thanks to TDR the wifi sleep issue is now fixed!
We have also fixed the under/overvoltage settings for 1.7 Ghz.
Missing from this release is Usb Mass Storage support. (Not usbOTG, where the Xoom is the usb host) In 3.2 we are able to access the external sdcard through the MTP protocol and removing support for this helps the stability of the usb connectivity on the xoom.
(USB Mass storage support is buggy)
We have also brought in a LOT of changes from nvidia with regards to bug patches and enhancements for the tegra platform.
Due to some of the changes by nvidia, when your device boots, after it displays the motorola logo it will show distortion before the boot animation. This is normal on this kernel and doesn't seem to effect the device at all.
You would of also noticed that we've moved to another thread from this release. This is to help differentiate between the 1.x.x series which is not supported on Android 3.2, and likewise with the 2.x.x on 3.1.
why "Removed the usb mass storage support. (being able to write directly to the external sdcard via your pc)", is there any problem arise from this?
EDIT : Sorry, didn't read your post. So excited actually. I also experienced reboot when connected to pc thru usb but i thought it's not the problem..hehhee.
EDIT 2: i don't know what wrong from CWM 3.2 after choose mount usb storage, i cannot see my external micro sd from my pc. I tried 2 times into recovery but still failed to detect my external sd card. If someone know the solution, please share with me. Because if i cannot find the solution, i cannot upgrade to this new kernel. Why? Because if i want to use my external sdcard, i will have to disable my 3g card just to remove the external sd card and connect it to my pc using micro sd card read.
