Public bug reported:

Hi,

I'm running Ubuntu 10.10 with all the latest updates.

When I download
http://showcase7.divx.com/mobile/Sintel_DivXPlusHD_2Titles_6500kbps.mkv
(that's a free movie) to a USB flash drive and try to play it on my
Panda (through the default movie player from the file browser), my
kernel oopses and freezes:

See the full boot log attached to this bug report.

Most of the time, the system freezes in this way, though it happened to
me once that the system survived. I could still move the mouse cursor,
but couldn't use any menu though.

Cheers,

Michael.
