It should have the fix for your i915 in the intel patches, along with a couple of radeon fixes, and the vblank change + fix.
I'm seeing some laptop screen flicker during boot and a while after I log in (it then seems to go away). It's my trusty old Macbook with i915 and Ubuntu 10.04. I see this in dmesg:
[ 1.782046] [drm] initialized overlay support [ 1.782075] [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state [ 1.782889] render error detected, EIR: 0x00000010 [ 1.782933] page table error [ 1.782970] PGTBL_ER: 0x00000102 [ 1.783009] [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010, masking [ 1.783063] render error detected, EIR: 0x00000010 [ 1.783106] page table error [ 1.783143] PGTBL_ER: 0x00000102
I'm attaching the full dmesg, i915_error_state, and .config.
Right, looks like we have an issue with setting up the hardware for KMS/GEM whilst it is still active. As we disable the outputs anyway for the KMS takeover, we can arrange to do so first and so prevent this bug. The side-effect will be that initial screen blanking will last a little bit longer.
I'm also seeing these errors now which seem to be new from 2.6.38-final:
[ 437.566022] [drm:i915_gem_mmap_gtt] *ERROR* Attempting to mmap a purgeable buffer [ 437.566187] [drm:i915_gem_mmap_gtt] *ERROR* Attempting to mmap a purgeable buffer [ 437.566232] [drm:i915_gem_mmap_gtt] *ERROR* Attempting to mmap a purgeable buffer [ 437.566275] [drm:i915_gem_mmap_gtt] *ERROR* Attempting to mmap a purgeable buffer [ 437.566318] [drm:i915_gem_mmap_gtt] *ERROR* Attempting to mmap a purgeable buffer
That's an old userspace bug, which so far no one has been able to reproduce on the upstream ddx. -Chris
