OHCI1394 hangs

[Krzysztof Halasa <khc@intrepid.pm.waw.pl>]

Hi,

2.4.9 UP kernel here, OHCI 1394 Exsys card + Sony DCR-TRV110E Digital8
camcorder. 440BX mobo.

The problem manifests itselt when I turn the camera off and then try
to load the ohci1394 driver. It halts with the following messages
(debugging on, hand-edited):

devctl: Bus reset requested
Get PHY Req timeout [0x0/0x0/100]
IntEvent: 20010
irq_handler: Bus reset requested
Cancel request received
IntEvent: 20000
IntEvent: 20000
(this message loops here)

The driver loads and works correctly when the camera is on or when nothing
is connected to 1394 bus.

Any ideas?
