For those seeing the crashdump issue, its after flashing the custom ROM version over a custom ROM?
For myself, no, and I've don't multiple clean flashes and it still would result in crash dumps no matter what. Back on the latest stock version and I've had zero issues. I mostly think it was due to the underclocking, as it would only crash dump when the screen was off and idling, but never during use.
i read its suppose to be better batterylife then hasty
I was getting great battery overall. I can't say better or worse as I've been mostly using Radioactive and not much else. I was aiming for low idle drain and would get anywhere from 0.25%/hr to ~1.0%/hr in most cases. Using this and naptime concurrently.

Thank you so much for taking the time to mod the kernel and for sharing your work.
I'm on T-Mobile OnePlus 8 running crDroid & this is by far the best performing kernel for me personally. Battery life is great, solid/stable, customizable but works great out of the box. A solid bonus for me is all my streaming services work with this kernel while rooted w/ Magisk.
Thanks again!

Same, I've been running this for about a month now and I encounter the same crash dump problem. Took me a while to narrow it down to the kernel. After going back to stock Radioactive, it hasn't crashed yet.
Crash dump? Never happened to me I use the kernel every day. Maybe on custom, I didn't write 99% of the code (I just added all the features from the OOS version to it) - blocked wakelocks, added Adreno Boost, changed the frequency clocks. The phone should be stable underclocked at 295 on both versions. I've seen kernels go as low as 180mhz in the past without a crash of any kind. Adreno boost will up the frequency if it's not handling the load.

I'm really not actively working on this build (I have a K40 Pro Plus I'm working on ATM, 888, Google is driving me insane on their new mandatory format of loadable modules on boot). Not even the most famous devs have built a kernel yet. I've been in touch with nearly all of them.

Thanks guys for the kind words from those of you that like my kernel. I've been running it all the time and it's never crashed on me. It's still a good habit to reboot your phone every day, or every few days. But I've only tested OOS since I don't run custom ROMs.

Sorry busy on other projects at the moment, no time to update to the newest release of Radioactive. Of course no one has paid me to do it, and I have an 888 phone now (Redmi K40 Pro Plus 12/256 from China, $600 delivered in 10 days to my house from China directly - PM me if interested, the place to order is 100% Chinese and my Chinese speaking friends can't even figure out how to order there, but somehow, I did thanks to Google Lens and Translate). I still use my Op8T 5G all the time though. It's a great phone.

    Can I get a link to try this? Tia
    This is a tweaked version of RadioActive kernel by acuicultor modded for higher performance and lower idle drain. All source commits and releases are on my GitHub fork:

    https://github.com/mrslezak/Radioactive_kernel_oneplus8/releases/tag/V2.1.4_GPUOC

    PLEASE read the Readme as well as the disclaimer. Whenever you flash a custom kernel, you do so at your own risk. I recently rebased on the dev's work (GPU_OC OOS branch, never released) and set the wakelock blocks up myself (lower idle drain, tested over a week with no loss in functionality), dropped the base GPU frequency to 295mhz and raised the top ones (800/920mhz) acuicultor you're an awesome dev, great to have you around! All credits should go to him other than my tweaks.

    I also merged all the same changes into the Custom ROM branch which didn't have GPUOC or AdrenoBoost - several people are using it now but it's marked as a BETA since I am on OOS (latest Global) and can't test it myself. NOTE: many people on the TG channel I posted to have tried it and have had no issues on Op8, Op8 Pro, and Op8T. They informed me it doesn't need a beta tag. The only issue reported (which I noticed on RadioActive 2.1.1) is that random read/write speeds are lower in AndroBench UNLESS you activate dynamic fsync. If you don't want to keep it on, all you need is 2 kernel managers - SmartPack is free. The first turns on dynamic fsync on boot (say 1-3 second delay), the 2nd turns dynamic fsync off (4-6 seconds delay). Then the Androbench random/read speeds will return to normal. Don't ask me where this bug came from, I just forked his kernel, and it's an easy fix.

    Note if you are one of the rare people who see artifacts in games or benches, the easiest fix is to go into your kernel manager and set the max GPU frequency to 800mhz and apply on boot. Not all 865 Adreno GPUs are created equal. I haven't seen one that couldn't handle 900mhz to date, but enough people have had no issues at 920mhz so that's where I put it.

    Be sure to flash Magisk Canary before installing, then use EX Kernel Manager or FK Kernel Manager to Flash the kernel zip. It has all the same optimizations of RadioActive kernel, just modded for really nice performance and low battery drain. Adreno Boost is set to low on default which makes it react faster as the GPU scales. If you already have Magisk installed, there is no reason to reinstall it - the AnyKernel 3 zip installer will use what's installed already.

    Hope you all enjoy!

    - MattOfTheDead / Red Magic 5G MOD kernel (Q) / Xiaomi Mi9 / Mi9T Pro MOD kernels (Pie/Q) / next in line is probably a Realme GT, once source is released.

    Can't wait until this is updated with the newest source!

    Modded Custom BETA is out with the same features of the OOS kernel in the post above. 295/800/920Mhz GPU, Adreno Boost with Low default, default Wakelock block list. Go to the same location to download if you'd like to try it out. And please, please read the DISCLAIMER there. Whenever you flash a kernel, you do so at your own risk. I am liable for nothing. If you want to see what I changed, switch to the custom branch. So far I have 5 people that have said "it's awesome" on Telegram, no issues reported as of yet.

    Now if you REALLY want to save battery and your cell provider supports Voice over WiFi, Google Messages enable enhanced chat features and keep it on WiFi only (i.e. Bluetooth only on while you're using it, Location off unless you're navigating somewhere, NFC off unless you're using GPay, mobile data off), here's what I get being on my phone all day today (started under 60% battery) at 120hz: 7% active drain, 0.84% inactive. If you're asleep it's more like 0.4%. You won't miss any calls or texts either.
