While we are at adding a quirk table entry for this controller --- could
you please test whether another common controller bug is present in this
device?

For the test, you need to have gcc installed, download this test tool:
http://user.in-berlin.de/~s5r6/linux1394/utils/test_cycle_time_v20100125.c
compile it with "gcc test_cycle_time_v20100125.c", and run it with "sudo 
./a.out /dev/fw0".

The program then runs (possibly silently) for 60 seconds and then prints
a test summary.  Please post this output here.

The controller bug which is being tested for concerns timestamps which
are used in industrial video applications and for audio I/O over
FireWire.  You can run this test without any devices attached to the
FireWire controller, or with arbitrary devices attached to it (storage,
video, audio --- doesn't matter for the test; and if you have a FireWire
disk attached, you can even leave it mounted during the test).

Even if you don't have any of those devices yourself for which this
potential other controller bug would be relevant, it would be nice if
you could run the test and report the result.  It could be of help to
other fellow Linux users who may have such a device combination.
