Re: [Xen-devel] disk offline with xen4.0+pvops2.6.31.13
we found some info from xen wiki:
Enabling MSI/MSI-X for Assigned Devices
As of Xen 3.4.0 MSI/MSI-X is always on.
This change was made in changeset: 18454:65dc37be0443
In Xen 3.3.0, MSI/MSI-X could be enabled using the xen boot parameter "msi=1".
This change was made in changeset: 18127:89d05940cc1c
The following snippet from a grub configuration enables MSI/MSI-X
kernel xen.gz msi=1
does it mean that we should also Enable MSI Support for SAS in mptbase module?
