Subject: BUG: unable to handle kernel paging request at virtual address


I got the following message, shortly followed by a system hang.
BUG: unable to handle kernel paging request at virtual address 48464443

(see the oops below).

I've been getting kernel oopses for quite some time now, ever since I
got a new computer (several months now).

The problem manifests when I use mplayer/mencoder to capture from
TV card (Avermedia 203, BT878 chipset). Doesn't matter if it's viewing
or encoding. Usually happens within first 2 hours of capturing, quite randomly.
Note that other system-intensive tasks (video encoding from file, 3D games,
heavy fs activity) don't cause any instabilities.

Reproduced with kernels 2.6.21, 2.6.22 and 2.6.23.12 (the first two
being on openSUSE 10.2, and the 2.6.23(.1 and .12) on openSUSE 10.3).
Unfortunately, I only have the oops output from 2.6.23.12.

Doesn't seem to be the memory problem (I tested it with memtest86),
and that other commercial OS seems to be working fine (well, at least
no hangs during capturing and no suspicious freezes).

The messages below indicate that I have a proprietary driver (nvidia)
loaded, but the kernel hangs without it too - using pure vesa framebuffer,
without running an X server.


mplayer command:
gmplayer -sws 2 tv:// -tv driver=v4l2:input=1:width=768:height=576\
:forceaudio:amode=1:adevice=/dev/dsp -mc 0


Hardware:
CPU: Athlon X2 5200+ (dual-core).
MB: Asus M2N-E SLI (nforce 500 chipset, latest BIOS update).
TV card: Avermedia 203 (BT878 chipset).
Ram: 2G Kingston
Video card: NVidia 8600GT (MSI)


The oops itself (from dmesg - I had its output logged every second, so it managed
to get saved before the real freeze several seconds later):
