Hi,

I am currently using Slackware 10.1 with 2.4.29 kernel and encountered following
problem:

I use Sagem Fast 800 ADSL modem of my provider and use my linux station as a
router (iptables+masquerade). The problem is that after a few hours of working
my linux crashes with the message:

"

<0>Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing"

I tried rekompiling the kernel and chose MMX architekture in "Processor Type and
Features -> Processor Family" but it did not help. I also tried different
versions of Sagem drivers but the problem is still present.

I am a newbie to linux and would be very thankful for any solutions or just
hints about solving this problem. I don't know if the problem is caused by
sagem drivers but on the second PC station (Athlon Xp2000+, 384 MB RAM, 80GB
Samsung) nothing like this happened.
