Known issue, please read the archives.

Also, no one seems to know what the problem is :(

Nor why it seems to only affect ieee1394, when nothing changed. Also it
seems to only affect -mm.

Nope. It happens with 2.6.3-rc2 here. (note no -mm part)
2.6.2 was fine. I will probably do more experiments to find out which patch
made this to happen.
