Sorry about that, I was unable to figure it out.

basically the trace loops at the end like this:

select(10, [3 4 5 7 9], [], [], {0, 199890}) = 0 (Timeout)
gettimeofday({1173870449, 572305}, NULL) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1173870449, 572389}, NULL) = 0
select(10, [3 4 5 7 9], [], [], {0, 0}) = 0 (Timeout)
gettimeofday({1173870449, 572569}, NULL) = 0
gettimeofday({1173870449, 572705}, NULL) = 0
gettimeofday({1173870449, 572753}, NULL) = 0
ioctl(3, FIONREAD, [0])                 = 0

I dont really know what 10 and 3 are, and was unable to find out.
This was the best I could do:

...
uname({sys="Linux", node="localhost.localdomain", ...}) = 0
socket(PF_FILE, SOCK_STREAM, 0)         = 3
....
open("/etc/passwd", O_RDONLY)           = 10

I'm kind of suspecting some network issue due to the socket call.
I verified I can ping localhost.localdomain though.

I've had some issues with ipv6 in the past and will try disabling that
as well.

As further info I notice that I'm sometimes able to start qjackctl if
I first start jackd manually.

This didnt work.

Its the same with the rt kernel, and the stock fc kernel.

I'm going to try if ndiswrapper works better, im currently using the
kernel bcm43xx module.

Is the same.
