Hi there,

I have the following firewire controller:

fwohci0: <VIA VT6306> port 0xc800-0xc87f mem 0xea004000-0xea0047ff irq 3 at 
devi
ce 12.0 on pci0
fwohci0: OHCI version 1.0 (ROM=1)
fwohci0: No. of Isochronous channel is 8.
fwohci0: EUI64 00:11:06:00:00:00:4a:1d
fwohci0: Phy 1394a available S400, 3 ports.
fwohci0: Link S400, max_rec 2048 bytes.
firewire0: <IEEE1394(FireWire) bus> on fwohci0


It works quite good with an IBM disk although I also get ack err messages from 
tiem to time. 

However when connecting a 80 GB Seagate disk and copying to the mounted 
partition I get lots of messages like this:
sbp0:0:0 No ocb(260d628c) on the queue

When booting from my rescue CD (FreeBSD 5.0 Current, created in April) the 
copy process seems to work fine despite the "No ocb..."-messages.

When copying from my current desktop system FreeBSD 5.1 Release I additionally 
get kenel panics, e.g. ffs_valloc: dup alloc.

In all cases: If  I do a fsck this works fine. No complaints from teh firewire 
point of view.

What should I do to get more meaningful informations which  I can provide to 
the developer when making a bugreport? Can I assume to be fine with FreeBSD 
4.8 STABLE?

Manfred
