Since this is also a bug in upstream kernel, I opened a report upstream.

Confirmed with 2.6.34 here, no hope, it's been like that for more than a
year...

upstream has made some changes in this area, here is the mainline kernel
build for ubuntu

Can you please try the mainline kernel and see if this problem still
exists?

This bug (crash of X between 10 to 60 minutes at the most) existed during the
whole lifespan of Karmic.
I'm still experiencing the problem as of 10.04 RC1 (with updates as of
4/28/10). My problem is exactly as described by the OP. No CRT monitor
is involved.

> Could it be different hardware?
All the bug reports are on i915.
My guess would be that intel_crt_detect gets called when a CRT monitor
is detected, while intel_tv_detect is for LCDs. Can anyone who knows the
driver comment on this?

[i915] Crash after suspending (NULL pointer dereference
Yeah, you're right, that could well be the same bug. But since we don't
really know what leads to one or another trace... Could it be different
hardware? In this case we could consider the traces as the same.

Oh yes, I see that now. But if the oops traces do point to the same bug,
then couldn't the same bug be causing the intel_tv_detect() NULL pointer
dereference? They have very similar stacktraces:
[] ? intel_crt_detect+0x69/0xe0 [i915]
[] ? drm_helper_probe_single_connector_modes+0x26e/0x300
[drm_
I think upstream were talking about the X trace, not the Oops, which is
the only way to get the real cause of the X crash.

OK, I will break the bugs apart into this one for intel_crt_detect() and bug
525801 for the intel_tv_detect(). However, from the upstream bug report, "The
userspace stacktraces are irrelevant, as any GPU hang or OOPS may trigger
such a trace -- that one identical symptom may imply any number of b
I don't think these are all duplicates. I've kept all the duplicates
where the oops happens in intel_crt_detect(), and created bug 525801 for
the ones in intel_tv_detect(). It seems Apport only considers the NULL
pointer dereference as the common part, but I fail to see how this can
ensure the bugs
A lot of people seem to be affected by this bug (see all the duplicates)
and it happens in a lot more places than just suspend and resume. The
call traces are very similar in a lot of the duplicates, except they
have intel_tv_detect on top, which I assume is a related function to
intel_crt_detect.
