Created attachment 65293 [details] dmesg I have a HP all-in-one machine with Celeron G530 that is not able to drive the panel properly (?). The image is flashing a lot, right after when kms kicks in. attaching dmesg with drm.debug=0xe and a short video of the flashing.
Created attachment 65294 [details] video that shows the flashing
this still happens with 3.6-rc1
Can you please attach lspci -nn for your gpu, too?
Created attachment 65296 [details] lspci -nn
Went to bet that it is an eDP-to-LVDS bridge? :-p
Can you please grab the latest intel-gpu-tools from git at http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/ And then please attach the output from tools/intel_reg_dumper both when kms is enable and when the i915.ko kernel driver is disabled (e.g. with i915.die=1 on the kernel cmdline).
don't have the machine anymore since I don't own it. But I'll ask the owner to run the reg-dumper. I'm afraid it'll just hang with nomodeset, but we'll see.
Timeout. Please do reopen if you can still reproduce the issue and help us diagnose the problem, thanks.
