The patch is necessary for x64 version of LSI SCSI drivers since it fixes the phase mismatch implementations. Linux doesn't have those issues since the jump registers 1 and 2 are the same. This was also true for 32-bit versions of Windows nevertheless Microsoft seems to change this to match specs in the x64 version of those LSI SCSI drivers. But it's great to hear it's working fine and this is not any other issue ;) Regards, Michal -- Michal Novotny, RHCE Virtualization Team (xen userspace), Red Hat
