Are you using qtjackctl or launching from a script/command line?

Subject: help, jackd crashing, don't know why

Hi,

I upgraded my ubuntu studio box to Lucid Lynx and now jackd is crashing.

Here's the log:

The result of uname -a:
Linux hdrec 2.6.31-11-rt #154-Ubuntu SMP PREEMPT RT Wed Jun 9 12:28:53
UTC 2010 i686 GNU/Linux

Current Ubuntu version: Lucid Lynx

Is there anything more I should be reporting?

Thanks in advance,
