firewire problem on 5.1-RELEASE

[Petr Holub]

Hi guys,

there's some new bug in firewire driver in 5.1-RELASE.
When I connect camera to ma Dell Precision 530 box
via firewire I get following messages:

fwohci0: BUS reset

After this when I try to read from camera I get following:

fwohci0: IR DMA overrun (0x40008011)
fwohci0: IR DMA overrun (0x40008011)
fwohci0: IR DMA overrun (0x40008011)
fwohci0: IR DMA overrun (0x40008011)

Can anybody help me? It used to work in 5.0-RELEASE so I suppose
it to be a new bug.

Thanks,
Petr

PS: Keep me in Cc: of your answer since I'm not a list member and
I won't be able to react promptly otherwise.
