Comment 98 for bug 541511

Created an attachment (id=34923)
excerpt from dmesg containing crash dump for i915_gem_object_put_pages+0x10b/0x110

A few updates. I have used a script running in background to gather DRI debugfs dumps.

1) the system is not totally hung up, because background scripts still run. Only keyboard/mouse die
2) it is the same crash happening with libdrm-2.4.18 and libdrm-git, so it's not libdrm-dependant
3) the nul bytes were due to write buffers not being flushed before hard shutdown, and with the 'sync' call in the daemon script (available in tbz archive) it correctly puts the crash dump in /var/log/messages
4) it does not only depend from wine but also from some other application, because I had to run wine and firefox to trigger it; anyway it looks deterministic and not totally random
5) the crash must have happened within the last 10 snapshots (e.g. seconds), sorry but I can't be more precise, I hope you can guess where it crashed from the DRI debugfs dumps

If I can be of some help I'd be glad to make other tests/reports; looks like I am able to reproduce this bug at will, so I can actually make manual tests.
