Hi,

it's about one year that I'm using my Native Instruments Audio Kontrol 1
(USB2 audio/MIDI interface) only with audio applications and it has been
working well so far.
Now I'm trying to use it with Rosegarden (MIDI) and, as soon as I start
Rosegarden, JACK crashes, the process jackd becomes "uninterruptible" and
with the command dmesg I find the following new lines

I already asked to the Rosegarden and JACK people, but they couldn't help
me: it seems to be a driver related problem, as I can happily use
Rosegarden if I run JACK with the internal Intel sound card.

The program versions I'm using are: jackd 0.116.1, rosegarden 1.7.2.

Here's some other outputs:

I do not include the jackd and rosegarden outputs becouse they are quite
long, but, if you think they are useful to understand what is going on, I
can send them too.

Any ideas?

Thank you
