ieee1394: sbp2: sbp2util_node_write_no_wait failed

[Michael Brade <brade@informatik.uni-muenchen.de>]

Hi,

I get the above message frequently while copying data (around 200000 mail 
files, 2GB) from my laptop to an external harddisk via ieee1394. The ieee 
system completely deadlocked with 2.6.13 without the chance to umount or 
reuse the device. Now I upgraded to 2.6.14-rc5 and I still get the error 
followed by a 10sec pause or so, but then the copying continues. I will have 
to check if it copied all data correctly, though.

When attaching the device this is what the kernel says:

kernel: ieee1394: Current remote IRM is not 1394a-2000 compliant, resetting...

And the complete error message:

[lots more of that, the command hex code changes everytime]

I have a preemt kernel:
CONFIG_PREEMPT=y
CONFIG_PREEMPT_BKL=y

and the 1000hz timer:
CONFIG_HZ_1000=y
CONFIG_HZ=1000
CONFIG_PHYSICAL_START=0x100000

and the following is the ieee config:
CONFIG_IEEE1394=m
CONFIG_IEEE1394_OHCI1394=m

CONFIG_IEEE1394_VIDEO1394=m
CONFIG_IEEE1394_SBP2=m
CONFIG_IEEE1394_SBP2_PHYS_DMA=y
# CONFIG_IEEE1394_ETH1394 is not set
CONFIG_IEEE1394_DV1394=m
CONFIG_IEEE1394_RAWIO=m
# CONFIG_IEEE1394_CMP is not set

Please tell me if you need more info, I'd like to provide all the help needed 
to fix this issue.

Cheers,
