Venkat,
 
Can you post the serial console output?

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?

Thx,

Venkat
