Subject: NULL pointer dereference at cfq_exit_single_io_context

Hi,

The attached dmesg is obtained on a 2.6.30.8 with:

- DRM patches mainly gathered from Fedora F-11 branch,
- The following patch from mainline which addresses kernel bugzilla #13401:

From: Jeff Moyer <[email protected]>
Date: Fri, 11 Sep 2009 15:08:59 +0000 (+0200)
Subject: cfq: choose a new next_req when a request is dispatched
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=06d2188644c85c56d243efab914f368d1d23c4a3


The user which sent me the dmesg below tells that consecutive attempts to boot into X with the *nouveau* driver is generally not possible because of random lockups.

I'll have access to the machine in this week so I can try anything you want me to do.

Thanks,
Ozan Caglayan

This problem should be fixed now, we debugged it for a long time. E.g.
https://bugs.freedesktop.org/show_bug.cgi?id=23847

The commit:
http://cgit.freedesktop.org/nouveau/linux-2.6/commit/?id=7798546495c04a810db86be34ba1f39e370fd325
"drm/nouveau: fix missized allocation for ttm_bo_global struct"

I hope that solves your issue.

Oh that's a nice clue. I will try with the patched kernel, thanks a lot!
