I don't get hard freezes/lockups, but i get a strange "stutterting", as if the whole OS halted for a few seconds, then continued for a few seconds...and the 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 vmid: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 behaviour right after startup until it finally worked again - for about 45min. As it didn't work again after around 10 reboots, i tried uninstalling corectrl (that i used to have a custom fan-curve) - and it finally booted normal again! 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° C hot before the 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 radeon-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?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
