[qubes-users] High CPU load and fan always-on with recent kernels

Mailing Lists qubes-users

Hardware: Lenovo Thinkpad P14s, latest BIOS

Kernel version

6.6.54-1.qubes.fc37.x86_64 and
6.6.48-1.qubes.fc37.x86_64

both show two problems:

a) Fan is on full speed all of the time.

b) Occasionally, one or several VMs show high CPU load although nothing particular is running. The system becomes sluggish to the point of not being usable anymore.

Kernel 6.6.42-1.qubes.fc37.x86_64 is fine, and all the versions before this one as well, as far as I can tell.

Any ideas?

If you run xentop in a dom0 shell, does it show a specific vm causing high cpu?

Possibly the VMs don't have sufficient RAM and are swapping to disk.

First impressions of the new 6.6.63-1.qubes.fc37.x86_64 are that the issue is gone. Moreover, it seems the system is more responsive than even with the last known good kernel 6.6.42-1.qubes.fc37.x86_64, but this remains to be seen over the next couple of days.
