as well as :

Dec 31 10:44:53 tux kernel: [drm:intel_panel_get_max_backlight] *ERROR* fixme: max PWM is zero.

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.

Hello, 

On Fri, 31 Dec 2010 10:52:48 -0500 (EST)

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

Hello Rafael,

On Fri, 31 Dec 2010 16:47:24 +0100

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!
