jackd crashes using freebob and Focusrite Saffire LE

[prismatic7]

Description: Ubuntu 8.04
Release: 8.04
uname: 2.6.24-16-rt #1 SMP PREEMPT RT Thu Apr 10 15:15:40 UTC 2008 i686 GNU/Linux

I have recently purchased a Focusrite Saffire LE firewire audio interface, which is supposedly supported by both freeBoB and FFADO, however I am unable to use the device. jackd either crashes after the timeout period, or jack-aware applications are not able to connect (see log below)

The system is a Dell XPS M1210. sudo lspci -v reports the firewire chipset as:

03:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller (prog-if 10 [OHCI])
 Subsystem: Dell Unknown device 01d7
 Flags: bus master, medium devsel, latency 64, IRQ 18
 Memory at ecbfd800 (32-bit, non-prefetchable) [size=2K]
 Capabilities: [dc] Power Management version 2

This is the output of qjackctl's verbose messages:
