There is a patch attached to the BZ report that has been ack'd by a 
couple of testers as well as by the original committer. I've been told 
that it should go through Eric Anholt instead of Dave Arlie, but Eric 
has yet to respond.

The regression still exists[1] in the mainline kernel -- the confirmed fix
mentioned below has not been committed.

Just got back to the machine in question.  It's gone in 2.6.35-rc6+ (can
we get rid of this stupid '+'?) by

    ACPI: handle systems which asynchoronously enable ACPI mode
 
So you can close the bug entry.

I actually haven't been able to reproduce with kernels since a couple
weeks ago (still reproducible if I go back to 2.6.35-rc3, though).
Seems to be fixed somehow, can anyone else confirm?

Just updated the bug for this one.  Enrico, you say this behavior is
recent.  Can you bisect between 2.6.34 and when the problem started?

Hi. I just tried, but can't find anything useful until now (surely it's 
my fault: it was my first attempt at bisection). Please let me try again 
in the next days.

I also noticed that interrupts keeps high in powertop. I bisected it
today:

The bisect stopped between d275f66 and 0f3ee80 so I reverted the
following three commits:

b3b095b drm/i915: enable LVDS on Cougarpoint
d275f66 drm/i915: Clear the LVDS pipe B select bit when moving the LVDS to pipe A.
0f3ee80 drm/i915: Allow LVDS on pipe A on gen4+

Now the powertop only shows about 0.2 interrupts per second. Hope this
information is useful.

Kanru

Hm that doesn't make much sense.  Can you collect register dumps using
intel_reg_dumper between the two cases?  I'd expect the LVDS to be on
pipe b after the revert, but maybe before the revert we're leaving pipe
b enabled and getting spurious interrupts?

If it works on Fedora, maybe you could get it working with a similar
upstream kernel (same version, same config) and then bisect?
