Bug#645785: [nouveau] unable to handle kernel NULL pointer dereference
Hi Jonathan, my chipset is NVIDIA NV46. Anyway, I did not manage to reproduce it either. So I think you may probably close this report. I will eventually open a new one.

Thanks; marking accordingly. What chipset do you use? Please attach /var/log/Xorg.0.log and dmesg output from just after booting. The invalid pointer dereference is in nouveau_fence_update(), dereferencing chan to compute chan-dev. chan is 0x1 (weird --- shouldn't a struct nouveau_channel be word-aligned?) and was obtained by dereferencing sync_obj (== fence).

Is this reproducible? If so, is it reproducible using the latest kernel from sid, without the virtualbox driver loaded (e.g., you can test by blacklisting it)? If both answers are yes, we should take this to http://bugs.freedesktop.org/, as described at http://nouveau.freedesktop.org/wiki/Bugs. If the first is yes and the second no, I suppose we can treat it as a virtualbox bug. If the first answer is no, we can analyze the data you've sent and hope it happens again. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?
