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.

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

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?
