Hi,
Since sometime now, I have an issue that I think is related to drm.
When using this machine, at one point I get the following type of
console messages:
drm:pid49171:intel_pipe_update_end *ERROR* [drm] *ERROR* Atomic update failure
on pipe A (start=77294 end=77295) time 219 us, min 1073, max 1079, scanline
start 1071, end 1086
drm:pid49171:intel_pipe_update_end *ERROR* [drm] *ERROR* Atomic update failure
on pipe A (start=79270 end=79271) time 178 us, min 1073, max 1079, scanline
start 1070, end 1082
After that, the system will get more and more sluggish to the point of
being unusable. Do you think it can be a hardware problem? Here is a
complete dmesg right after boot:
