Bug#607484: upgrade-reports: unusable on intel i810

2011-11-23 Thread Jonathan Nieder
Hey Mario,

Sorry for the long lull.

 X freezes on a regular basis on i810 graphics, with messages like this:
 [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
 render error detected,
 EIR: 0x
 [drm:i915_do_wait_request]
 *ERROR* i915_do_wait_request returns -5 (awaiting 62 at 61)

There have been some fixes for GPU hangs in the meantime.

[...]
 the workaround is:

 Option Shadow true
 in the xorg.conf Device section.

 to reproduce this bug, use:
 x11perf -range copywinpix10,comppixwin500 -time 1 -repeat 1

Thanks for providing a reproduction recipe.  Can you still reproduce
this?  What version of the kernel and of xserver-xorg-video-intel do
you use?  Any other news?

Thanks for your help and patience.

Sincerely,
Jonathan

 Shadow is enabled by default on 845, so that shouldn't make any
 difference.

that can not be the case.

I updated to the experimental distribution video driver (and X server), which 
does not even start up without Shadow true.
with Shadow true I had no freezes whatsoever using experimental, so this 
bug is fixed in experimental. however, it is not fixed in unstable. I still 
had some freezes with that version, even with Shadow true.

without the Shadow option the experimental X server shows a mouse cursor 
and a black screen only, with rendering errors in the X log.

no other packages have been updated (same kernel version). only 
xserver-xorg-video-intel and its dependencies were updated.

Bug#607484: upgrade-reports: unusable on intel i810

2010-12-20 Thread relative
the upstream bug is:
https://bugs.freedesktop.org/show_bug.cgi?id=26345

as you can see in the report this was reported many times and appears to affect 
all 845G chipsets, so please do not ship squeeze without a fix or the following 
workaround. it took me about 30 reboots to figure this out.

the workaround is:

Option Shadow true
in the xorg.conf Device section.

to reproduce this bug, use:
x11perf -range copywinpix10,comppixwin500 -time 1 -repeat 1

this appears to be a xorg bug, not a kernel bug. please change the assignment.

 That output just says the gpu is hung, which can have an infinite number
 of different causes.

I realize that, but there is no more information in it. it is the only message 
since booting.

 
  lspci:
  00:02.0 VGA compatible controller: Intel Corporation
 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
  
  Xorg.log:
  
 That's still not the full X log, and you didn't provide the full dmesg.

?
except for some redacting that`s the full log.


I understand that this is not a lot of information to reproduce the bug, but 
please consider that this appears to be a KNOWN bug, so all debian has to do is 
to ship a version that doesn`t have this bug and/or disable kernel mode 
switching.
