[Xen-users] page fault for mpt2sas in domU ?

[Pierre Peyronnel <pierre.peyronnel@xxxxxxxxx>]

Hi everyone,

new subscriber here, and fairly new to Xen.

I have managed to install a dom0 (alpine 2.7) and a domU (debian 7.0)

I am trying to pass through my LSI 8i controller to the domU but the driver does not load correctly with a page fault (see below) but is visible in lsmod.

If i boot using the regular kernel in alpine (instead of the Xen kernel) it woels like a charm and i can see al my disks (see below the first log).

I could not help but notice that the regular alpine kernel loads a 64 bits driver v14 while the debian domU loads a 32 bits driver v10

Any help appreciated

Pierre
