This is a message from the kernel during resume which is printed after

Yes, I found the corresponding source file. BTW: it's a hand-compiled
kernel, so if it helps to add some extra line in the corresponding
function to print which tasks are restarted, I can do that. However, I
would be happy if someone could tell me _what_ to change in the source.

Ah. Another thing worth trying (if the ohci1394 is not the problem) would
be to do a "powersave -l" before suspend. There were problems with ondemand
during suspend/resume and we worked it around at some point by just switching
to a fixed cpu frequency during suspend. Not sure if your powersave version
already does that, but doing "powersave -l" before suspend will ensure that
it is on the lowest cpu frequency. However, i doubt this is the problem since
that would also hit you when manually suspending. We never know, though :-)
Does not help either, sorry.
So if a patching power/process.c to print some extra information might
help, I could do that. In any case, the " done\n" ending the function is
not printed any more, so the problem must occur somewhere there.
Thanks,
Norbert
