[linux-dvb] Expert Oops interpretation wanted

[Emard <emard@softhome.net>]

Gotcha

Here are ksymoops interpretation of the blinking leds crash.
Some background: I used lowest irq 5 solo for DVB Satelco/Budget,
latest CVS sync's and carefully adjusted PCI latency of all 
cards in my system to satisfy each card's required minimum 
latency. (Requrement #1 for PCI latency)... Now,

After cca 30 min of running, it crashed again. I catched the 
oops and decoded it with ksymoops.

Can you tell from given output what kernel option/module crashed 
the system and what should I add or remove to stop it from further 
crashing?

ksymoops 2.4.5 on i686 2.4.20.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.20/ (default)
     -m /boot/2.4.20/System.map (specified)
