What's your scsi host controller?

The disk controller is just onboard SATA (a dell optiplex 745)
from lspci:
 IDE interface: Intel Corporation 82801H (ICH8 Family) 4 port SATA IDE Controller
Full lspci from the working ubuntu linux kernel attached.

USB is known to have problems, so I generally disable it for now, until I've worked out what's failing.  You have an oops in your trace which could be leaving other things in a bad state.

I can't disable USB completely since the system I am using doesn't have any PS/2 ports.
I did a test boot without USB
I built a fresh kernel, since I got the previous one in a really bad state, but the new
kernel I just built is not doing well either.

I just did a defconfig + all the xen options

Attached is 4 boot attempts, all with nousb, and also trying to disable the usb in the
2nd and 3rd and turning USB back on in the 4th.

So I am guessing I am running into a driver issue at this
point. I will dig around more and compare my working
vanilla linux config with the dom0 kernel to see if there
is something missing in my dom0 kernel.

Yes, that would be interesting to compare.

I still need to look at this more closely and build the kernel more
carefully based on a working one.

Thanks for playing with this.


I still got a lot more testing I can do tomorrow.
I'll keep in touch and thanks for your efforts
on the pv_ops dom0 kernel
