firewire disk stopped working

[Boris Kotzev]

My external firewire disk "Seagate FreeAgent Pro" stopped working with CURRENT 
from today. It used to work without any problems before today's update.

After plugging the cable the following error messages begin scrolling on the 
console continuously:

sbp0:0:0 sbp_scsi_status: unknown scsi status 0x0                                                                               
sbp0:0:0 Obj: Data buffer, Error: Type error                                                                                    
sbp0:0:0 sbp_scsi_status: unknown scsi status 0x0                                                                               
sbp0:0:0 Obj: Data buffer, Error: Type error                                                                                    

They stop only after the cable is unplugged.

Is there any way to make the disk work again?
