I think you can remove this one from the regression list. I've received an
update from Florian that said !

--- Comment #27 from Florian Mickler <florian@mickler.org>  2011-02-20 10:52:15 ---
According to #22652 "*ERROR* Attempting to mmap a purgeable buffer" warns about
a userspace error.  

It links to ticket #22652 in which Chris Wilson indicates this is warning
about userspace bug, and that this issue is tracked in :
https://bugs.freedesktop.org/show_bug.cgi?id=31419

So, this definitely looks like the problem is not in the kernel (though my
personal view on this is that the message itself should be made much more
clear and reflect that the problem is not in the kernel, but in userspace).

Thanks for the tracking you've made,
Paul

Ok, I'm closing this bug. 

If the error messages go away if you update your userspace (maybe
someone can advise if your versions are 'old', I currently have no
overview of whats current), and you still experience problems (like
those Xserver crashes or freezes), then we should reopen the bug
though.

It seems it got fixed. I have no clue which of the two commits in the relevant
files could possibly fix it, but my adapter works now, with current git version
(493f3358cb289ccf716c5a14fa5bb52ab75943e5).

Thank you

With regard

OK, currently running :

Nope... machine is booting fine, screen is Ok, and in fact the machine
seems to be working perfectly... The only point is that I never saw these
in any kernel prior to 2.6.37-rc1, and them being labelled as "ERROR" made
me write a report.

Anyway, if some can tell me how to get this linus'tree, I'm ready to give
it a try Sunday afternoon.

There were some last-minute fixes related to i915 added to the Linus' tree
after 2.6.37-rc8.  Perhaps you can give them a try?
