[Xen-users] problem with capture card exported to dom-u

[Moses Leslie <marmoset@xxxxxxxxxxxxx>]

I have a 4 port bt878 capture card that I'd like to export to my dom-u.
It appears that pciback is working correctly, the line I've got in grub
is:

module        /boot/vmlinuz-2.6-xen root=/dev/sda1 ro console=tty0 
pciback.permissive 
pciback.hide=(03:04.0)(03:04.1)(03:05.0)(03:05.1)(03:06.0)(03:06.1)(03:07.0)(03:07.1)

(4 video and 4 audio ports on the capture card).

I get, for example:

pciback 0000:03:04.0: seizing device

So I think this part is working correctly.  When I boot up the dom-u with
the PCI options with the following PCI option:

pci=['03:04.0','03:04.1','03:05.0','03:05.1','03:06.0','03:06.1','03:07.0','03:07.1']

I can see the devices in the dom-u:

fs1:~# lspci
0000:03:04.0 Multimedia video controller: Brooktree Corporation Bt878
Video Capture (rev 11)
0000:03:04.1 Multimedia controller: Brooktree Corporation Bt878 Audio
Capture (rev 11)
0000:03:05.0 Multimedia video controller: Brooktree Corporation Bt878
Video Capture (rev 11)
0000:03:05.1 Multimedia controller: Brooktree Corporation Bt878 Audio
Capture (rev 11)
0000:03:06.0 Multimedia video controller: Brooktree Corporation Bt878
Video Capture (rev 11)
0000:03:06.1 Multimedia controller: Brooktree Corporation Bt878 Audio
Capture (rev 11)
0000:03:07.0 Multimedia video controller: Brooktree Corporation Bt878
Video Capture (rev 11)
0000:03:07.1 Multimedia controller: Brooktree Corporation Bt878 Audio
Capture (rev 11)
fs1:~#

However, when I halt the domain, it locks up as if it's having an issue
with the 3ware controller that the dom0 is using.  It says intially:

Sd 0:0:0:0: WARNING: Command (0x2a) timed out, resetting card

Then, after a while it says:

sd 0:0:0:0: rejecting I/O to offline device

over and over.  If I hit return, there's an ext3 error about sda1.

Is there something I'm doing wrong in my configuration, or anything else I
can try?

Thanks!

Moses
