Good Morning!
NOTE: Please CC answers/replies to my personal email account, because i can't keep
track of all the stuff on linux-kernel, as i just started a new job. Thank you very
much!
Ok i'll try to stick to the bug report form :)
PROBLEM: Kernel Panics since i switched to T-DSL, using masquadering. Supposed to be
fixed in 2.4.5pre9 ?
Description:
I switched to DSL about 2 weeks ago, i got 3 NICs in that box one for the private net,
one for the biz net and one for the DSL modem, using pppoe (not rp-pppoe). All three
are Intel EtherExpress Pro 100+, two brand new ones and an older one (different size,
same driver), but it happened with a Tulip card instead of the old Intel (which serves
the modem) as well. The Kernel kept crashing with Kernel Panics, usually with Process:
swapper (PID = 0), but when dnetc is running, it preferrable gives dnetc as process.
It seems to occur only with masquadering in use.
I'm using Kernel 2.4.6 (it happened in 2.4.4, 2.4.5 and 2.4.5ac22 as well), because i
thought those fixes in pre9 would od the trick:
-pre9:
- make sure "sync()" doesn't effectively lock up the machine by
overloading all the IO resources
- fix up some network memory allocations that don't wan tto wait on IO.
it crashed only two times in a little more than 24 hours, which is really good.. I was
happy for every hour uptime the days before :) I hope the other informations help you
to find and fix the problem, i'll be happy to provide any other information needed.
Keywords: Kernel Panics, sync(), IO ressources
(i think ;)

Couldn't figure out how to do the oops tracing (it's late) and i can't provide a shell
script/program which reproduces the crash unfortunately, it dies unexpectandly.

Kernel panic: Aiee, killing interrupt handler!
In interrupt handler - not syncing.
Well people, i really hope you can help me with that problem, i know that i'm not the
onl one, a friend of mine has the same problem, and another guy in the adsl4linux
Forum.
http://www.adsl4linux.de/forum/viewthread.php3?TID=147
He even has a screenshot of his kernel panic (this one has Process: swapper ;), look
quite similar to mine.

That's it, i'm going to bed.. Have fun dudes, and don't make me switch to *BSD ;)
