The 2.6.23 kernel built for mips with the attached .config works fine for me
under qemu (both big endian and little endian), but a 2.6.24 mips kernel
segfaults initializing the ne2k driver (again when run under qemu).

I've traced it to this commit:

http://kernel.org/hg/linux-2.6/rev/74258

Version 74257 works, 74258 does not.

The qemu invocation is:

qemu-system-mips -M mips -no-reboot -nographic -hda /dev/zero -kernel \
vmlinux -append "panic=1 console=ttyS0"

The panic is:

Linux version 2.6.24-rc2 (landley@driftwood) (libc/sysdeps/linux/mips/crt1.S:

Kernel panic - not syncing: Fatal exception in interrupt
Rebooting in 1 seconds..

The final 2.6.24 release panics slightly differently, it waits until the ne2k
init and then loses it. I'm not quite sure this is the same problem (since
the error is now occuring in a different place), but I haven't found any
kernel _after_ that which won't panic during init. Only the placement of the
panic changes.

I fiddled around a bit in the debug menu, but didn't figure out how to get
actual function names of out a mips trace...

The way I reproduce this is with my http://landley.net/hg/firmware/ build
script, download the most recent version (links to tarballs at the top),
run "./build.sh mips" and let it grind a lot, then extract the
build/qemu-image-mips.tar.bz2 tarball, cd qemu-image-mips and
run "./run-mips.sh" in that directory. (I have qemu 0.9.1 installed.)
