BTW: yet another thing that might help chasing the problem.
It behaves in very deterministic way. I've built the firewire
as module to be able to use the machine normally and I have
found following behavior:
(without X)
kldload firewire
(no problems)
startx
(interrupt storm)
kldunload firewire
(no problems)
kldload firewire
(interrupt storm)
kill X
(no problems)
So it occurs deterministicaly when both firewire and X
are loaded. Unloading any of them (or both of them ;-) )
helps.
