kintsugi reborn.

Based on my previous project, Kintsugi, kintsugi reborn follows its predecessor's goal to give the device a good balance between performance and battery life while focusing on its stability for a daily life usage. Features and changes are carefully chosen and pulled from different other kernel projects.

Features
  • Built with Google Clang version 12.0.6 + LLD linker
  • Full -O3 build with chipset's flags included (thanks to kdrag0n)
  • AnyKernel3 powered installation to stay OTA and flashers (EXKM, FKM...) friendly
  • ARM architecture performance and battery patches
  • Disabled numerous debug and logging options
  • Disabled several Samsung security and debug related options
  • Implement SafetyNet flags patches by sultanxda and kdrag0n
  • 250 Hz timer frequency
  • BPF JIT compiler enabled by default
  • Implent CPUfreq backports by celtare21 (KuranKaname on XDA)
  • Westwood set as the default TCP network congestion control
  • ZEN v2 set as the default I/O scheduler
  • Disabled Kernel Samepage Merging by default for less CPU usage
  • Built-in Boeffla wakelock blocker with pre-configured wakelock blocklist
  • exFAT and vFAT filesystems support
  • Implent sdFAT mount options by cocafe
  • WireGuard support
  • Other misc. optimizations and fixes

After flashing and rebooting, my device keeps on restarting and does not boot into the OS. Downloaded the .zip twice to make sure that the file didn't get corrupt when downloading. This looks like an amazing kernel and can't wait to use it once this issue is hopefully fixed.
Exactly the same issue here.

Thanks for letting me know. I will fix that issue as soon as possible because I know where it comes from.

yes it's not working on one UI


That's false.

The download link has been updated. I would like to know if the issue got fixed whenever you've got time for testing it out.

The download link was not updated however it showed me the updated file (https://sourceforge.net/projects/kintsugi-reborn/files/kintsugi-reborn-stable#2.10-2.zip/download) but unfortunately flashing the new file did not fix the issue. But thank you for the time you took trying to fix it, hopefully you could find the root cause soon. Is there any logs or anything that I could provide to assist?
