|Well i'm experiencing some problems and i dont know if are all related to the same issue.
The first comes after boot, and is these message:
kernel [ 10.691412] [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.
it cames 4 times, but i can change my brightness with Fn keys with no problem.
After that i looked my syslogs and saw two more 'drm' ERRORS, these two:
kernel [ 850.349538] [drm:i915_gem_mmap_gtt_ioctl] *ERROR* Attempting to mmap a purgeable buffer
kernel [ 3331.440501] [drm:i915_gem_object_bind_to_gtt] *ERROR* Attempting to bind a purgeable object
and that at xorg log
intel(0): intel_uxa_prepare_access: bo map failed: Invalid argument
all these errors came all time, but the thing that is bad to me is that X (kde) sometimes freezes and i must restart to work. I dont know if that it's related with the other ERRORS or not....
Reading i saw that some people had the backlight error too, but it seems that the update to kernel 2.6.37-0.slh.6 worked for some... i'm at slh.18 and nothings change.
Anyone has some info about?? same problem???
Thx in advance and sorry for my englis!!
