[linux-dvb] Expert Oops interpretation wanted
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)
