I have reproduced similar problem. Did you use NFS when the problem
occured? I think the laptop's TX buffer is stalled.

NFS seems to generate mbuf with zero data size and this stops
some OHCI chips with unrecoverable error.
I have committed a fix to -current. Could you copy -current's
/sys/dev/firewire and /sys/modules/firewire then test it?

I have no idea about your strange EUI64 problem yet.
