Summary: Hotplugging a USB device causes an unrecoverable kernel Aiee!
Copied from screen after interrupt handler killed, so sorry for
incompleteness. This
bug is reproducable so if necessary, I can try it again....
kernel BUG at slab.c:1402!

.......
Kernel panic: Aiee, killing interrupt handler!
Sorry for the incomplete data. The system doesn't write anything to logs
about the crash, since it is a pretty hard one, but I can reproduce this
bug
if it hasn't been reported yet (I didn't find it in archives) or the
above is
insufficient.
More data:
AMD K6-2 400 processor, >200MB memory
Gnu C 2.96
Binutils 2.10.0.18

The complete oops report is required, and it needs to be run through
ksymoops. See Documentation/oops-tracing.txt.

It's a known problem, I think. USB is incompatible
with slab redzoning. Turn off `Debug memory allocation'
in the kernel hacking menu.
