SubjectHow to get backtrace? modprobe -r iwlagn; modprobe iwlagn kills kernel
Date
Hello,

I'm having some problem getting a backtrace. When I do "modprobe -r iwlagn;
modprobe iwlagn" (2.6.38.6 with Intel-1030N) the kernel crashes (sometimes I
need to try 2 or 3 times, and sometimes the modprobe -r is the one that
crashes).
This spams my monitor with several oops/panics before it finally dies. I can
only see bottom of the last one, which probably isn't very meaningful.
I tried loading netconsole, but I only get one or two lines before it stops
sending/printing.
I then tried kexec+crashkernel, but I only managed to get a backtrace for the
last panic (which I think is just a result of memory corruption or something).
Finally I tried compiling ramoops into my kernel, but it didn't want to load
because of "No such device".
