Hi,

since my upgrade to openSUSE 11.0, which comes with 2.6.25.4, soon after I start using my DVD player, I get the following in the log:

DRDY == device ready, and it occurs billions of times per day during normal use.

There is no "famous DRDY issue", you are simply seeing timeouts.

Have you tried all of: pci=nomsi, acpi=off, or noapic?
