I started getting this error message after connecting a monitor via (mini)displayport. If i turn the monitor off or it goes to sleep it kills my desktop session and i can only get a picture back by switching to VT1-6 |
Created attachment 160341 [details] dmesg output from 3 resume cycles Using a Radeon R9 270X and kernel 3.18.0 I get the following error message only after resume from S3 state: [drm:si_dpm_set_power_state] *ERROR* si_set_sw_state failed I would like to notice that this also happened with older kernel versions (3.17 and 3.16 with radeon.dpm=1) and other cards. My other PC has a HD 5450 with the same problem (slightly other ERROR string as its not SI). Besides the error message, I cannot see any strange behaviour, performance is good, no freezes etc. . But it sounds like performance level switching is not working correctly? I added the dmesg output showing three resume cycles with the mentioned error message as attachment. Thanks
