firewire problem (root node is not cycle master capable)

Hello,

I'm runnig -current from one week ago.
Today I tried to use my Firewire external enclosure, which worked flwalessly 
some time ago with -current.
But now I only get the following:
fwohci0: BUS reset
fwohci0: node_id=0x8800ffc0, gen=25, non CYCLEMASTER mode
firewire0: 2 nodes, maxhop <= 1, cable IRM = 0 (me)
firewire0: root node is not cycle master capable
firewire0: bus manager 0 (me)
fwohci0: too many cycle lost, no cycle master presents?

Any hint's what I can do?

fwohci0: <Texas Instruments TSB43AB23> mem 
0xf9104000-0xf91047ff,0xf9100000-0xf9103fff irq 18 at device 6.0 on pci5

fwohci0: Initiate bus reset
fwohci0: BUS reset

Thanks,
