Re: Firewire bus problem?



Basically this indicates a hardware problem somewhere, but we can't pin it down from the information below.

It could be a bad PCI card, a bad FireWire cable, a bad DV device - or a combination of devices that may each be near the edge of the spec, and together they can't get along. It could also be an "environmental" problem like noisy AC power, ground loops, nearby Tesla coils... I would try swapping out individual devices and see if a difference can be identified.

I'm not positive, but I believe 8009 is an older TI OHCI, so the PCI card may be an old model. A newer one might work better.

It's unlikely this is caused by any software issues or corruption.

Hello,

I have a user who keeps getting these system logs appearing along
with the the failure to operate of my application. I've not had any other
users have this problem so I'm wondering if he has some kind of hardware
problem or maybe his OS installation has corrupted in some way.


These are the logs:

Oct 11 22:38:53 eric-jones-power-mac-g4-agp-graphics kernel[0]: FireWire (OHCI) TI ID
8009 PCI: Bad selfIDs, issuing bus reset (retry 2)

He claims he has one Firewire port which doesn't work at all and so he
has tried a PCI card, but that generates these logs and still won't allow
my application to work.


Is anyone able to shed any light on what these logs might mean? Is his
DV device (being controlled by application) faulty perhaps?

Regards,

Tim.
