The problem has been observed only on platforms with the CMD646 IDE controller
revision >5. You can verify the controller information from the OBP:
{2} ok devalias
Alias Device Path
--------------------------------------------------
xdisk /ssm@0,0/pci@18,600000/scsi@2,1/disk@0,0
xnet /ssm@0,0/pci@19,600000/network@2
cdrom /ssm@0,0/pci@18,700000/ide@3/cdrom@0,0:f
disk /ssm@0,0/pci@18,600000/scsi@2/disk@0,0
<snip>
Take the cdrom line & “cd” down the device tree stopping before the /cdrom@.
{2} ok cd /ssm@0,0/pci@18,700000/ide@3
{2} ok .properties
assigned-addresses 81001810 00000000 00000300 00000000 00000008 81001814
<snip>
At the end of the .properties output you will see controller vendor, device and
revision specific info. Similar to:...
revision-id 0x7
device-id 0x646
vendor-id 0x1095
The above example shows 646 as controller & revision 7 i.e. This platform is at risk. |
