Default Bug#616559: BUG: soft lockup - CPU#1 stuck for 63s!

Package: linux-2.6
Version: 2.6.37-2
Severity: normal

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi. Log files in /var/log gets loaded with messages seen below (CPU#1
stuck for 63s!), when my computer is supposed to be idle - meaning
computer in not used for 15 minutes and monitor is off. But instead
fans keep spinning like wild and log files growing.

Default Bug#616559: BUG: soft lockup - CPU#1 stuck for 63s!

I can reproduce this on an openSUSE 11.4 system (kernel
2.6.37.6-0.11-default) with integrated Intel graphics (82865G, device
ID 0x2572).

mihkel, are you using a KVM switch by any chance? I do, and I have
found that the bug only happens when the KVM is switched to my other
machine. As long as the KVM is switched to the machine with the integrated
Intel graphics, everything is fine. Do you observe the same?

Thanks again. This is said to be fixed by the attached patch, which
comes from Intel's drm-intel-testing branch[1]. That branch does not
feed directly into linux-next but patches there tend to end up in the
drm tree eventually.

The bug is said to be a regression introduced in 2.6.30-rc8. Does
that match your observations?

If you get a chance to test the patch against 3.0.y or 3.2.y, that
would be very helpful.

Hope that helps,
Jonathan

Subject: drm/i915: fixup load-detect on enabled, but not active pipe

commit e95c8438ea1c56c254f0607c8fb6bca7f463c744 upstream.

Somehow we have a fast-path that tries to avoid going through
the load-detect code when the encode already has a crtc associated.
But this fails horribly when the crtc is off. The load detect pipe
itself manages this case well (and also does not forget to restore the
dpms state), so just rip out this special case.

The issue seems to go back all the way to the commit that originally
introduced load-detection on the vga output:

commit e4a5d54f924ea5ce2913d9d0687d034004816465
Author: Ma Ling <ling.ma@intel.com>
Date: Tue May 26 11:31:00 2009 +0800

drm/i915: Add support for VGA load detection (pre-945).

Default Bug#616559: BUG: soft lockup - CPU#1 stuck for 63s!

Here's a blind backport to 2.6.32.y. I'd be interested to hear
whether the kernel in squeeze is affected, and if so, whether this
patch helps and has no bad side-effects.

FWIW, I did backport the patch to kernel 2.6.37.6, and it fixed the
issue, with no bad side-effect.
