I checked the BBS, but I didn't immediately't see anything related.
Any ideas?
A guess,
First - what model laptop/CPU?
It's a Sager/Clevo NP8852P. $ grep Intel /proc/cpuinfo|sed 2q vendor_id : GenuineIntel model name : 12th Gen Intel(R) Core(TM) i7-12700H
I ask because if I recall correctly, one of the changes the 6.10 kernel brought it was "improved" scaling of CPU core speed. This would have been from the release notes either from The Register or Phronix. My only thought is you may have a CPU/chipset, or or passing kernel parameters on boot that isn't playing nice with the new CPU scaling preventing your core processor speed from idling down.
(top would still show 100% idle -- but your CPU may be idling a 3.5GHz)
You can check if your cores are idling down with:
grep '^processor\|^cpu MHz' /proc/cpuinfo
processor : 0 cpu MHz : 400.000 processor : 1 cpu MHz : 400.000 processor : 2 cpu MHz : 400.000 processor : 3 cpu MHz : 400.000 processor : 4 cpu MHz : 851.190 processor : 5 cpu MHz : 400.000 processor : 6 cpu MHz : 400.000 processor : 7 cpu MHz : 400.000 processor : 8 cpu MHz : 1083.960 processor : 9 cpu MHz : 400.000 processor : 10 cpu MHz : 1006.537 processor : 11 cpu MHz : 400.000 processor : 12 cpu MHz : 942.949 processor : 13 cpu MHz : 968.000 processor : 14 cpu MHz : 1361.782 processor : 15 cpu MHz : 1400.012 processor : 16 cpu MHz : 400.000 processor : 17 cpu MHz : 400.000 processor : 18 cpu MHz : 400.000 processor : 19 cpu MHz : 1384.733 And I just re-opened the lid to check for activity on my post.
If your cores are running at full-speed, this may be an area worth further investigating.
Bingo. My issue isn't resolved, but I at least I have something to go on. Thanks, David. Regards, Dan
