I believe it means that the firmware in the ARM processor on
the card has crashed.

A friend of mine is seeing this very often during normal
use of vdr.
I can reproduce that error easily when editing vdr recordings
(see the list archives).
It also happens here when I switch between play, pause, fast
forward and fast reverse too quickly.

I tracked the problem down once and found out that a certain
OSD ioctl is always the last command to the dvb driver before
the ARM crashes. Unfortunately, the driver developers have
little interest in the OSD, so it is unlikely that they will
fix this.  :-(
IMHO, it is the most annoying remaining bug.
