sbp2 driver in 2.5.72

sbp2 driver in 2.5.72

[Douglas Gilbert]

It works on my hardware in 2.5.72 but when the sbp2 module
is loaded, there is a 20 second delay followed by this in
/var/log/messages:
   ieee1394: sbp2: Error logging into SBP-2 device -
                   login timed-out
It immediately retries the login which works and then
all is well. Additionally the sbp2 driver doesn't like
the CONFIG_DEBUG_SPINLOCK_SLEEP option set in the kernel
build. Perhaps a spinlock is being held during that 20
second delay.


 From dmesg:

occurred): 0800FFC0
