Kernel panic - not syncing: Fatal exception in interrupt
Please remove me from the CC list, at least until you've discovered
ksymoops.
Sorry for that. Is this one more helpful?
No, you seem to be using the wrong System.map and/or vmlinux image.
Read the manpage, please.
Why do you think they are wrong?
Both files (System.map and vmlinux image) come from the kernel which panicked.
It could be I compiled the kernel by adding one module (no compiled-in the kernel changes) to its .config - without flashing the kernel. Would it make a difference to System.map and/or vmlinux image and ksymoops?
If so, here is one more try, where everything should be proper.
This panic was made by simply doing the below ~50 times in a loop, and is reproducible:
rmmod prism54
modprobe prism54
ifconfig eth2 up
If it's still totally wrong, please take my apologies, but I've no idea what I may be doing wrong.
