Subject: PROBLEM: i915 modesetting - weird offset graphics (v2.6.37-rc1-27-gff8b16d)

Folks,

I upgraded the userspace on my EeePC 1015PEM netbook to the latest
Fedora (F15) rawhide and booted a custom kernel in order to test both
the RC1 and also see if the now in-staging brcm80211 behaves better (it
doesn't, it still can't survive suspend at all, separate issue though).

The xrandr output is identical in both case, showing a mode of 1024x600
being the one that X is currently using. Booting with i915 modesetting
disabled does avoid the weird offset but of course X doesn't start. I
can bisect this if there isn't already some suggestions from the
audience, in particular is to what debug information you need.

Kernel: v2.6.37-rc1-27-gff8b16d

Said system will likely be at plumbers in the am...

I'll bring it in to Plumbers in a few hours.

Also, the intel-gfx list is moderated with auto-rejection. Do I really
need to subscribe to the list just to get a mail through?

I took it to Plumbers and pinged a few people in person, but nobody was
all that interested. I am bisecting this at the moment, a few builds in.

Thanks. I requested the k.o BZ to send me a new password over the
weekend, which was delayed by a few hours and then I didn't get around
to this. FWIW, the bug has a fix on the intel-gfx list.

Jon.
