I have logged your report as
	https://bugzilla.kernel.org/show_bug.cgi?id=16452
	nodemgr, sbp2: NULL pointer dereference in sbp2_update
but set its status to WILL_NOT_FIX for now.

The bug seems to be in the nodemgr component of the ieee1394 core
driver.  This is one of the things that were rewritten from scratch in
firewire-core with a fundamentally different implementation, for good
reasons.

Perhaps somebody else wants to look into a possible fix for this bug,
but this seems very unlikely.  (Basically, a bug fix already exists in
the form of firewire-core.)
