If you have nothing in your local logs, try to redirect the kernel
output to a serial port and capture it on a second box over null-modem.

What about addr2line -e vmlinux -f c01d68b2?

/proc/ksyms?

I still got no oops here, even with LAPIC on (one of the major
differences in our configs). Maybe I will try your original config later.

But there is definitely something fishy about
adeos-ipipe-2.4.32-i386-1.2-05: my Linux clock runs about twice as fast
as it should. This doesn't happen with a comparable 2.6 setup. I still
need to check what happens without CONFIG_XENO_OPT_TIMING_PERIODIC...
Uuh, what's this now? The oops, just with "inverted" .config! And it's
inside qemu - no chance to escape then. 8)

Ok, will keep you posted!
