Hi to you all !
Since I've installed proxmox in a machine with an AMD Ryzen 5900HX, there are some lines in dmesg that I've found to be of concern (maybe I'm wrong, but since I have no idea ... I'm concerned ^^´)
Here's the suspicious lines, first one is about the clocksource, no matter what I tried as grub options (here I tried clocksource=hpet), I end up with this :
[ 2.143851] clocksource: timekeeping watchdog on CPU3: Marking clocksource 'tsc' as unstable because the skew is too large:
[ 2.144876] clocksource: 'hpet' wd_nsec: 512439779 wd_now: 1bfdeb0 wd_last: 14fe9bb mask: ffffffff
[ 2.145670] clocksource: 'tsc' cs_nsec: 508608042 cs_now: af982f886 cs_last: a94e7f1d5 mask: ffffffffffffffff
[ 2.146130] clocksource: 'hpet' (not 'tsc') is current clocksource.
[ 2.146366] tsc: Marking TSC unstable due to clocksource watchdog
[ 2.146607] TSC found unstable after boot, most likely due to broken BIOS. Use 'tsc=unstable'.
This do not prevent proxmox to work, but if you have an idea to solve this, I would gladly try it.
The other one seems even more ominous :
[ 6.440799] UBSAN: invalid-load in drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:6039:84
