Kernel 6.6.0 - Higher thermals and kernel boot log errors

1) Flashed the microSD card a while ago, then transferred to the NVMe 2) Running a stable Linux 5.10 system with packages up to date with apt-get upgrade 3) Decided to try kernel 6.6.0 after your experimental release, but decided to build kernel myself with instructions from here: https://github.com/Joshua-Riek/ubuntu-rockchip/wiki/Building and using sudo ./build.sh --board=orangepi-5 -m 4) used the deb file in the build folder and dpkg -i to my system dpkg -i linux-image-6.6.0_6.6.0-ga482e8129726-1_arm64.deb 5) I was able to boot from NVMe with kernel 6.6 without issues, noticed is is running quite fast... details here: https://www.reddit.com/r/OrangePI/comments/17ld7zd/orange_pi_with_joshua_riek_and_kernel_660_amazing/ 6) however noticed that the thermals are about 8C higher.. is that normal / expected? 7) also a couple of errors on kernel on boot: https://pastebin.com/F6KSzVXJ

Expected: similar benchmarks, same avg CPU temperature and no significant kernel errors Actual: improved benchmarks, increased CPU temperatures and kernel errors that may or may not be significant

Keep up with the great work!
