I have had problems like this with the SBP2 driver since ~2.5.75 when I
attach (or sometimes when I attempt to mount) my 250 GB external drive. 
This never used to happen with 2.5.73 or earlier though.  

Sometimes the driver seems to go into an loop of "unsolicted packet
received" messages and attempted resets.  Here's what the log looks like
when that happens:  (this was on 2.5.75)

(this sequence repeats until I turn off or unplug the drive.)

I have not tried every kernel release along the way, so I don't know
exactly when the problem started.  It is also interesting that I have
not observed this problem when I use a 120 GB drive in the same firewire
enclosure.

Here's another snippet from the dmesg of my most recent boot, into
2.6.0-test1-ac3.  Luckily it didn't go into the infinite error loop this
time, but it did get one of those unsolicited packet errors:
