Please attach your xorg log and dmesg output. I think the error message is a result of a GPU hang probably caused by a problem is the mesa driver. If you can reliably reproduce this by only changing the kernel (not the userspace components), can you bisect? "[191856.414365] [drm:si_dpm_set_power_state] *ERROR* si_restrict_performance_levels_before_switch failed" was the only interesting line in dmesg and I had restarted X twice before I noticed it, so sorry (Gentoo only keeps current and last log). I changed to 3.19rc2 on the off-chance that it's dpm changes would solve this and I have not yet got any crash or such error. I turned on and is running with "options drm debug=0x06" now so I will be able to post more useful information if/when this happens again. I am using the same mesa version so if the problem lies therein then it may show up again. I guess it would be best to ignore this bug and let it sit here for a few weeks. I (or someone else) will need to get another X crash with this error to make any progress. If no such crash happens with 3.19rc2 (or what later version I may switch to) within weeks then perhaps it is solved. I've been getting this since January, when I switched to open source drivers. DPMS is completely broken (at least on dp port, which is all I've tried) and I've had to turn of all display power saving just to use. My dmesg shows a two additional lines, too. [ 4.583144] [drm:si_dpm_set_power_state [radeon]] *ERROR* si_restrict_performance_levels_before_switch failed [ 4.624808] [drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery reached max voltage [ 4.624835] [drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery failed I would love to contribute to the resolution of this issue. Please let me know how I can help. Created attachment 123976 [details]
dmesg
I have no xorg.conf file. Only 00-keyboard.conf in the .d dir.
This 3 year old bug is probably fixed years ago given that it involves a 3.x series kernel and mesa 10.x. I don't have a Radeon 7800 anymore so I couldn't provide any information even if it's not. |
