So ebx is an invalid pointer, it's the ixl_execp member of
hci1394_iso_ctxt_t.
[0]> ::offsetof hci1394_iso_ctxt_t ixl_execp
offsetof (hci1394_iso_ctxt_t, ixl_execp) = 0x38 <=====

We may do more investigation from this isoch pointer.
The second argument of hci1394_ixl_interrupt() is from
hci1394_isr_isoch_it():
ctxtp = hci1394_isoch_xmit_ctxt_get(
soft_state->isoch, i);
hci1394_ixl_interrupt(soft_state, ctxtp,
B_FALSE);
Looks to me like a 1394 problem.
