I have a laptop with the following firewire hardware:

    ~$ lspci
    03:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller

Running on the following kernel:

    ~$ uname -a
    Linux studio 2.6.27-3-rt #1 PREEMPT RT Mon Oct 27 03:05:19 UTC 2008 
i686 GNU/Linux

I followed the instructions in the wiki with regard to configuring 
real-time support 

I had to create /dev/raw1394 via the following command:

    ~$ sudo mknod -m 666 /dev/raw1394 c 171 0

I started jackd from the command line and the following errors are returned:

~$ /usr/bin/jackd -R -P60 -p128 -dfirewire -r48000 -p64 -n3
no message buffer overruns
jackd 0.109.2

I've googled these errors to death.  Based on my report above can anyone 
help narrow down the scope of my problem?
