Hi list,

I try to pass a Promise Ultra133 TX2 to a PVM.

On the PVM I can see the controller using lspci

"06:00.0 Mass storage controller: Promise Technology, Inc. 20269 (rev 02)"

But I cannot access /dev/hdaX because dmesg shows

"ide: Assuming 66MHz system bus speed for PIO modes
PDC20269: IDE controller at PCI slot 0000:06:00.0
PCI: Enabling device 0000:06:00.0 (0000 -> 0003)

pnp: the driver 'i8042 aux' has been registered
pnp: the driver 'i8042 kbd' has been unregistered
pnp: the driver 'i8042 aux' has been unregistered"

My dom0 has no problems accessing this device, and the domU boots the same kernel and initrd.

The Kernel version is the latest stable from xen.

Can somebody tell me whats wrong?

Thank you and best regards
