I think it is still there.
I use a CompactFlash Card as IDE-Drive without a pin for DMA on the CF-IDE
adapter. This is inside a Jetway J7F2WE-EDEN MiniITX-Mainboard (with VIA
processor). On this hardware runs UBUNTU Jaunty 9.04 with Kernel
2.6.28-11-generic. After booting the kernel immediately hangs 3-times for about
30 sec's with the following messages:

and further the system boots up normal with / on sdc1 (type xfs), swap on sdc2
(sdc = 16GB CF-Card).
I try to boot with kerel param "ide=nodma" and also the new "hd0=nodma" (is
that correct?) but always same behavior.
hdparm -i /dev/sdc outputs for DMA:
DMA modes: *mdma0 mdma1 mdma2
I would be interested on a kernel patch, which does not try the various
DMA-Modes.
Thank You.
