Still with us on -rc6, nasty, reproducible, no clues on what can be.
VC switch locks or delay the systems minutes, resuming from suspend locks
hard the machine.
2.6.28-rc is unusable here.
Jesse, any hints? My suspicion that it can be the same thing happened with
bug 10620 is wrong? (It was a very similar error about vblank...)
Just added to the bug, it looks like a DUP of an issue Keith just fixed last
week (now to make sure the patch makes it upstream quickly).
I can confirm that, with the patch from
http://lists.freedesktop.org/archives/intel-gfx/2008-November/000614.html
applied on top of current git head (rejected hunk in
drivers/gpu/drm/i915/915_irq.c due to the additional
dev_priv->irq_mask_reg = ~0; in git between the removed lines, I kept
it) I can suspend/resume and do a VC switch again.
Big thanks!
Bernhard
