Hello,

I have a problem using an external firewire harddrive. When writing to
the disk (badblocks -w) I get an error message about every minute:

kernel: ieee1394: sbp2: sbp2util_allocate_request_packet - no packets
available!
kernel: ieee1394: sbp2: sbp2util_allocate_write_request_packet failed
kernel: ieee1394: sbp2: aborting sbp2 command
kernel: Write (10) 00 09 51 b4 4a 00 00 fe 00

This by itself is - except for small pauses once and then - no problem.
But when writing much data (dd for 40 GB), it gets worse after some
time:

(log continued)

I am using kernel.org's 2.4.20 kernel.

Thanks for your help!
