Since my usb2 disk enclosure is working in lk 2.5.60
I tried my firewire (ieee1394) enclosure. The attached
oops occurred during 'modprobe sbp2'.

My kernel's .config has most debug options turned on.

#
# Kernel hacking
#
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_STACKOVERFLOW=y
CONFIG_DEBUG_SLAB=y
CONFIG_DEBUG_IOVIRT=y
CONFIG_MAGIC_SYSRQ=y
CONFIG_DEBUG_SPINLOCK=y
CONFIG_KALLSYMS=y
# CONFIG_DEBUG_SPINLOCK_SLEEP is not set
CONFIG_FRAME_POINTER=y

Looked at sbp2.c for a while but couldn't find anything.
A few 2.5 versions ago someone on the lkml reported that
sbp2 was working but I haven't had any success.
