Hi Randy,
I am attaching the complete output in a
file.
But for your reference, a part of it I am
pasting in the body.
==================================================================================

(XEN) PCI add device 00:1b.0
(XEN) PCI remove device
02:0e.0
==================================================================================
02:0e.0 is the pci id of Megaraid SAS
controller.
For some reason you can see that the
device is removed.
I guess this output would give you some
idea.
Thx,
Venkat

Venkat,
Can you post the serial console output?

Subject: Megaraid SAS driver
failing in Xen-3.3.0 but was working in Xen-3.2.2-rc3
On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller)
driver is not loading correctly if vtd support in Xen is enabled.
It fails at the point of initializing firmware.
I wasn’t seeing this error with Xen-3.2.2-rc3 (Unstable
version), though with vtd disabled in Xen-3.3.0, it is working.
Looks like a degrade problem.
Any clues?
