Thanks Ryan,
I tried the fix but it just gave a different symptom. (same error,
different variable)
Can you post the exact error message you're getting?
So... rpm --erase xen JIC there were any ghosts around. Manually
removed all traces of xen from the system. Then did a ./install.sh from
the xen-3.0.2-2 directory, which had a clean "make world".
The results are the same.
I've found a more generic error about a local variable being used before
assignment, but I think it's referring to dev_config.
Again, this only happens on auto-boot or domU reboot, and only when
there is a "pci =" line in the domU's definition file.
Any ideas how I can help debug this?
Can you post the output of /var/log/xend.log? If your file is large,
please don't attach the whole thing! :) Specifically, I'm interested in
any errors in the file and the debug lines that contains the words
"XendDomainInfo.create" followed by some information in lots of square
brackets. Also take a look at the kernel log in dom0 (type 'dmesg') and
look for any strange errors.
I've found an area in the log that _may_ show where the problem arises.
Let me give a refresher. There are
1 pci slot: 00:0d.0
2 vif's on 2 bridges: LAN, DMZ
3 vbd's: hda1, hda2, hda3
On a boot the following devices are created in this order:
hda1, hda2, hda3, pci, LAN, DMZ
On a reboot the following devices are created in this order:
LAN, DMZ, hda1, hda2, hda3
Note that the pci device is _not_ recreated on a reboot.
The following excerpt from xend.log shows the pci creation in a
successful boot. This code never happens in a failed reboot.

Will keep digging....
Is the pci device appearing correctly in your domU? Do you see any
strange error messages or warnings in your domU before you try and
reboot it?
