I've got a machine which has been dying repeatedly with nothing loged to
the serial console we could see. The problem was the console would kick
you off if idle for too long. I managed to keep one it from
disconnecting for quite some time and finally got a panic. I caught
this:

Can someone please tell me what this means or how to figure it out? The
machine is offline for the next 12 hours unfortunately due to lack of
remote help. I do have similar machines with the same kernel/hardware
if I need to run any commands against this output. I don't have access
to any specific files on the machine though.
Thanks,
Robert

Feeding that Oops to ksymoops at your running machine _might_ help,
but if you use modules, it is somewhat less likely to succeed, as
module loading may end up at different memory locations.
Plain numeric Oops definitely does not help.

This document is mailed to lkml regularly and will be modified
whenever new victim wishes to be listed in it or someone can
no longer devote his time to maintainer work.
If you want your entry added/updated/removed, contact me.
BTW, requests to move your entry to the top of the list
without actually changing the text are fine too: that
will indicate that entry is not outdated, so don't be shy ;-)

So, you are new to Linux kernel hacking and want to submit a kernel bug
report or a patch but don't know how to do it and _where_ to report it?
Preparing bug report:
=====================
*** Remember: bad/incomplete bug report ONLY wastes bandwidth! ***
How To Ask Questions The Smart Way:
http://www.catb.org/~esr/faqs/smart-questions.html
Anybody who has written software for public use will
probably have received at least one bad bug report.
Reports that say nothing ("It doesn't work!");
reports that make no sense; reports that don't give
enough information; reports that give wrong information.
How to Report Bugs Effectively:
http://www.chiark.greenend.org.uk/~sgtatham/bugs.html
Before asking a technical question by email, or in
a newsgroup, or on a website chat board, do the following:
* Try to find an answer by searching the Web.
* Try to find an answer by reading the manual.
* Try to find an answer by reading a FAQ.
* Try to find an answer by inspection or experimentation.
* Try to find an answer by reading the source code.
Compile problems: report GCC output and result of
"grep '^CONFIG_' .config"
Oops: decode it with ksymoops (or use 2.5 with kksymoops enabled ;).
Unkillable process: Alt-SysRq-T and ksymoops relevant part.
Yes it means you should have ksymoops installed and tested,
which is easy to get wrong. I've done that too often.
Sending bug report/patch:
=========================
* Some device drivers have active developers, try to contact them first.
* Otherwise find a subsystem maintainer to which your report pertains
and send report to his address.
* Small fixes and device driver updates are best directed to subsystem
maintainers and "small bits" integrators.
* It never hurts to CC: Linux kernel mailing list, but without specific
maintainer address in To: field there is high probability that your
patch won't be noticed. You have been warned.
* Do not send it to all addresses at once! This will annoy lots of people
and isn't useful at all. It's a spam.
* Do NOT send small fixes to Linus, he just can't handle _everything_.
He will eventually receive it from maintainers/integrators, send it
their way.
* If your patch is something big and new, announce it on lkml and try
to attract testers. After it has been tested and discussed, you can
expect Linus to consider inclusion in mainline.

Could have been someone removing a module without unregistering an
interrupt handler. But that's just guessing.

You don't specify which kernel this is, it appears to be 2.4 something.
Please run this through ksymoops (man ksymoops)

This is 2.4.18 with the 2.6.5 i2c modules. The only modules enabled are
for the i2c and everything else is compiled in static. There was no-one
on the box the times when it went down and no messages about modules
being messed with either. I have about 30 of the servers out in the
wild all 99.9% identicle and there is only 1 having this issue which is
why my first thought it hardware.
This week I'm upgrading the puppies to 2.4.21-ac4 with the 2.8 i2c.

<0>Kernel panic: Aiee, killing interrupt handler!
1 warning issued. Results may not be reliable.
This is a dual 1.5Ghz AMD, 1Gig of ram, kernel 2.4.18 with i2c version
2.6.5. Everything but the i2c is compiled in staticly. Out of 35ish
machins which are identicle this is the only one leading me to believe
something hardware related, any reliable guesses as to what/why?
And thanks for those taking the time to help,
Robert

It looks like someone freed a tasklet without removing it. But considering
your kernel cocktail (imported i2c code) it makes it harder for us to
debug, perhaps if you could try on a newer kernel (i know it'd be hard to
do if it's production)

It is production. This week these systems go to 2.4.21-ac4 with the
2.8.0 i2c. I only think it's not a straight up kernel bug because there
are 35ish identicle systems running all the same software with 0
problems. In addition for some odd reason this one machine was giving
some very odd temp readings.

Not sure, note that EIP=0x80xxx and not 0xC0xxx.
