Xen devel - Oct 2008 - mptsas driver failing in Xen-3.4 unstable version

On Xen-3.4 (unstable version), I have created CentOS PV guest and dedicated 1068
SAS controller but I am not able to see the disk which is connected to 1068 SAS
controller when I do fdisk -l (vtd support is enabled in Xen).

Looks like the pci device(SAS controller) is getting dedicated successfully as I
can see the device in the list of pci devices shown by lspci.

05:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express
Fusion-MPT SAS (rev 08)

However the driver is not getting attached properly and fails with the following
error

=====================================================================Fusion MPT
SAS Host driver 3.04.05
                PCI: Enabling device 0000:05:00.0 (0000 -> 0003)
                mptbase: ioc0: ERROR - Unable to map adapter memory!
                mptsas: probe of 0000:05:00.0 failed with error -22
=====================================================================
Any clues??

Thanks,
Ramesh
