ieee1394: sbp2: sbp2util_allocate_request_packet

[Sebastian Zimmermann]

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)
kernel: ieee1394: sbp2: aborting sbp2 command
kernel: Read (10) 00 08 b3 f2 5a 00 00 fe 00

kernel:  I/O error: dev 08:02, sector 67838426

I am using kernel.org's 2.4.20 kernel.

Thanks for your help!

Sebastian

This is fixed the patch I send against -pre5. You can use the
branches/linux-2.4 directory in the repo as a direct replacement for
drivers/ieee1394 in fact (www.linux1394.org).

	It looks like the download page
(http://www.linux1394.org/download.html) is out of date:

"See below for how to apply patches. 

                   patch for 2.2.16-2.2.19 (released 2001-05-27) 
                   patch for 2.4.2-2.4.4 (released 2001-05-22) 
                   No patch is needed for newer 2.4 kernels and 2.5. Get 
the latest version of this series or use svn."

	I couldn't find a branches directory in the nightly tarball 
link at http://www.linux1394.org/viewcvs/trunk/?root=Linux+IEEE-1394 .

	Obviously I'm doing something wrong. :-)
	Is there some page on linux1394 which contains either a tar of the 
current 2.4 tree or a the most recent patch against 2.4?
	My sincere thanks for all your work and help.
	Cheers,
	- Bill

It's viewcvs (or viewsvn in this case). Browse the repo above (trunk
being HEAD). Unlink CVS, SVN stores branches in simple copies. The URL
you want is:

http://www.linux1394.org/viewcvs/branches/linux-2.4/?root=Linux+IEEE-1394


Then click on the tarball link at the bottom.
