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

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

[BUG] kernel BUG at slab.c:1402! -- 2.4.2-0.1.28

2001-03-21 Thread Greg Billock

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!
invalid operand: 
CPU: 0
EIP: 0010: []
EFLAGS: 00010086
eax: 1b ebx: 26d6a4 ecx: 81 edx: 14

ds: 18 es: 18 ss: 18
Process swapper (pid: 0, stackpage= c0289000)
...
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 C2.96
Binutils 2.10.0.18
Linux C library 1.92.so
Procps 2.0.7
Mount 2.10m
Net-tools (2000-05-21)
sh-utils 2.0

Modules: 8139too, nls_iso8859-1, nls_cp437, vfat, fat, usb-ohci, usbcore
