	Hello, I've just tried to test 2.6.0-test1 with IDE TCQ on,
and I've got the following Oops during boot, just after discovering
the first IDE drive (IBM DTLA 45GB). Rebuilding without
CONFIG_BLK_DEV_IDE_TCQ fixes the problem (altough I still have problems
with LVM on 2.6.0-test1).

	More info on both hardware and software of this box is available
on request.
