Panda board freezes reading a .mkv video

[Michael Opdenacker]

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.
