Have you tried higher/lower period sizes?

It might have something to do with a bug/issue present in the firewire
stack related to output ISO streams. There is a fix for this in the
2.6.26 kernels.

The issue manifests itself in the kernel not requesting any outgoing ISO
  packets anymore. Hence the jack process cycle doesn't run anymore and
jack aborts.

I have seen this happen with some cards, but only on a PCI express
system (dell d820). With the on-board controller and with a based
XIO2200 1394 expresscard.

However it could also be something else.

I would recommend that you install FFADO to drive the saffire LE, since
FFADO has a lot more verbose debugging output, and more checks to catch
this kind of issue.

http://www.ffado.org/?q=node/613 might help you install it.

Then join the ffado-user mailing list to further discuss this.
