Still not fixed. As I mentioned, the revert of
5c12a07e8073295ce8b57a822f811ac34e4f8420 missed some lines. I'm not familiar
with the hardware or the code, so I'm not sure if this patch is right. At least
it solves the bug for me. Chris any objection to re-adding it?

git bisect identified

[305e6835e05513406fa12820e40e4a8ecb63743c] sched: Do not account irq time to current task

as the cause of this regression.  Reverting it from 2.6.37-rc4 (requires some
hackery due to subsequent changes in the same area) restores sane behaviour.

(Author of original patch cc:d.)

The original patch submission talks about irq-heavy scenarios.  My case is the
exact opposite: UP, !PREEMPT, NO_HZ, very low irq rate, essentially 100% CPU
bound in userspace but expected to schedule quickly when needed (e.g. running
top or ps or just hitting CR in one shell while another runs a compile job).

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?

  if this is in any way related to various systems booting to a black
screen (as i described earlier), i built an absolutely up-to-date
kernel from the latest tree and that didn't solve the problem.  i'm
open to testing suggestions.

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.

Best,
Paul

OK, currently running : 
[root@tux ~]# uname -a
Linux tux.DEF.witbe.net 2.6.37-rc8-00014-g3643e0e #1 SMP Sun Jan 2 16:25:04 CET 2011 x86_64 x86_64 x86_64 GNU/Linux

and I've seen that too :
Jan  3 08:27:30 tux kernel: [drm:i915_gem_mmap_gtt_ioctl] *ERROR* Attempting to mmap a purgeable buffer
Jan  3 08:27:30 tux kernel: [drm:i915_gem_mmap_gtt_ioctl] *ERROR* Attempting to mmap a purgeable buffer
Jan  3 08:27:30 tux kernel: [drm:i915_gem_mmap_gtt_ioctl] *ERROR* Attempting to mmap a purgeable buffer
Jan  3 08:27:30 tux kernel: [drm:i915_gem_mmap_gtt_ioctl] *ERROR* Attempting to mmap a purgeable buffer

So, two possibilities :
 - 2.6.37-rc8-00014-g3643e0e is not what you wanted me to test,
 - the problem's still there.

Best,
Paul

I think it's still there.  Thanks for testing!

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-sVu6HhrpSfRAfugRpC6u6w@public.gmane.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.

Flo
