from Matthias M=C3=BCller
I don't know if i'm encountering the same bug, but it is at le=
ast similar.
I don't get hard freezes/lockups, but i get a strange "stutterting&quo=
t;, as if the
whole OS halted for a few seconds, then continued for a few seconds...and t=
he
halted times grew while the "usable seconds" got shorter quickly =
to the point
of unusability...
It doesn't happen regularly (seems like anything between 30min and 120min) =
and
i haven't yet made out a direct cause, but in journalctl, it seems the same
messages appear every time when it begins:
kernel: amdgpu: [powerplay] Failed to send message 0xf, response 0xfffffffb,
param 0xfd6000
kernel: amdgpu: [powerplay] Failed to send message 0xf, response 0xfffffffb,
param 0xfd6000
kernel: amdgpu 0000:0f:00.0: [mmhub] VMC page fault (src_id:0 ring:169 vmi=
d:0
pasid:0)
kernel: amdgpu 0000:0f:00.0: at page 0x0000600000fd6000 from 18
kernel: amdgpu 0000:0f:00.0: VM_L2_PROTECTION_FAULT_STATUS:0x00041152
after that there are a lot of these:
kernel: amdgpu: [powerplay] Failed to send message 0x40, response 0xffffffc2
param 0x2
kernel: amdgpu: [powerplay] Failed to send message 0xe, response 0xffffffc2,
param 0x80
until shutdown/hardreset.
Maybe some observation that might help to narrow it down:
The first time it occured, i had to do a few reboots that showed this behav=
iour
right after startup until it finally worked again - for about 45min.
As it didn't work again after around 10 reboots, i tried uninstalling corec=
trl
(that i used to have a custom fan-curve) - and it finally booted normal aga=
in!
I then installed radeon-profile to have fan-controll (i don't want to have =
the
fans stand still on desktop, as the card gets over 80=C2=B0 C hot before th=
e fans
kick in...).
The issue still occurs with radeon-profile, but at least every reboot is
running fine...
Other thing i noticed is that after the first "freeze" with radeo=
n-profile
lm_sensors stopped reporting the fanspeed for the card, it always stays at
zero.
So maybe it is related to fan-control or the sysfs interface in general?
