The "panic" i can force on the faster machine by 
recording on both cards.

The second card was recording since an hour
and issuing "MPEG1" from time to time.
(vdr-0.96  dvb-20000923)
Then i start a record on the first card: boom!



This time i generated ksyms to get a slight clue 
where it oops. (That might not be the module where the error
is.)


Oops: 0002

btw:
i can't see the "fsck /dev/hda4" any more :-)
is there an -easy- way to convert at least the dats
partition to reiser-fs? (ideally without loosing the data)
