Posted: Fri Sep 03, 2004 10:18 am Post subject: Kernel Panic: Howto figure out the exact reason?

Hi

I'm still having Problems to get my system stable

What I have is a mostly running system which randomly freezes while being online, it happens when there is some load over my dsl card and gives an:

Code:

Kernel Panic: Fatal exception in interrupt
In interrupt handler - not syncing

What I know is that it must be some problem with traffic over my dsl card - what I want to find out is what realy is causing this problem - hardware conflicts, driver problems, etc...

hopefully someone can give me some hints how to figure out. I tried to compile fcdsl with debug option and looked at dmesg and my syslog but there are no messages which look like there is some problem... only those that everything is running

(edit: the last time I got one error loged -> please have a look at my 3nd post down here)

so long
pi

PS: I already started a thread (Kernel Panic while having traffic over fcdsl-card) but no solution jet
only to prevend misunderstandings: This thread is hopefully more general. So a final solution whould be great, but general informations about solving kernel panics are absolutely welcome, too

My System:
P3, Realtek ethernet, AVM Fritz!DSL

Please tell me if there are other logfiles I should look for

As I mentioned before - after setting the system online it takes some random time of network load on ppp0 until the system crashes.

well, i'm not a kernel hacker but it looks like that something is not doing what it should, so i sugest that you send the log to the package mantainer.

@r3pek you're propably right and I'll try to get someone of the developers from avm - fcdsl is not officially in portage but back to my question: what exactly is causing the kernel panic? Those Fritz!DSL cards realy don't belong to "exotic" hardware in germany and there are enouth people running them with gentoo. So I should be able to get them running - maybe there is a stupid hardware-conflict I missed out or some problem with nptl or other compile options. Is here anyone who can give me some hints how to track down kernel panics in general?

maybe someone could help me with this more specific question: How can I view the whole call trace? Everytime the system crashes I got a call trace, but I'm not able to see more than the last page (which is quite sparse as the server is running without any framebuffer at default videomode)

I habe a similar error with a AVM FritzX USB ... almost I want to halt the pc, the kernel panic comes. The drivers are also für Suse 9.1 and from AVM but for the AVM FritzX ... maybe they are for a special kernel of suse? I don't know ...
