sbp2 driver in 2.5.72

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:
ohci1394_0: SelfID received, but NodeID invalid (probably new bus reset occurred): 0800FFC0
