Title:
Resume from suspend fails on new FireWire stack (TSB43AB22/A IEEE-
1394a-2000 Controller)
Status in linux package in Ubuntu:
Invalid
Bug description:
Since upgrade to 10.10/kernel 2.6.35 kernel doesn't complete resume
from suspend.
$ uname -a
Linux sendell 2.6.35-27-generic #48-Ubuntu SMP Tue Feb 22 20:25:46 UTC 2011
x86_64 GNU/Linux
Xorg vty is blank, I can change to other vtys but when i return to the one
with Xorg, switching no longer works.
Only manual reset remedies this situation.

And then resuming from suspend works.
I've browsed
https://ieee1394.wiki.kernel.org/index.php/Source_Repositories
to see if any recent fixes were made and this one sticks out:
http://git.kernel.org/?p=linux/kernel/git/ieee1394/linux1394-2.6.git;a=commit;h=dd23736e092035b71df1117482b71fdfb5634239
I'll shortly try
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38-rc8-natty/
to see if the mentioned commit or perhaps another one helped with this issue.
