You mean the tree available with :

svn checkout svn://svn.linux1394.org/ieee1394/trunk/ ieee1394 ?

Because i tried with checkouted revision 867 few minutes ago and i still have the "bad: scheduling
while atomic!" message when i rmmod the modules ( modules init tools were upgraded to 0.9.11a)

DV camcorder still doesn't seem to work ( with dvgrab for example )

# dmesg
oot is not IRM capable, resetting...
ieee1394: Remote root is not IRM capable, resetting...
ieee1394: Remote root is not IRM capable, resetting...
ieee1394: Remote root is not IRM capable, resetting...
[message repeated 178 times and as long as the DV Camcorder in turned on]
ieee1394: Remote root is not IRM capable, resetting...
ieee1394: Remote root is not IRM capable, resetting...

Starting to rmmod the 1394 modules:

dv1394: shutdown...
dv1394: stop_dma: already stopped.
dv1394: shutdown complete
dv1394: shutdown...
dv1394: stop_dma: already stopped.
