[BUG] firewire: mass-storage i/o-problems

[Andreas Messer <andreas.messer@stud-mail.uni-wuerzburg.de>]

Hello,

I tried the new firewire stack with a external harddisc and a external dvd 
writer and get massive i/o problems. Here is the kernel output for the 
harddisc. Please cc me for further questions. I hope its not too much output 
for lkml email.

using old fw stack, everything fine:

-------------------------------------------

Hardware: 
Via ohci1394 FW Controller (PCI), nforce2 chipset, Athlon XP-M

Software:
Kernel Vanilla 2.6.22, gcc 4.1.2. 

On another PC same problem, but replugging one or two times get the thing 
working.
