[1.] 2.2.17 hangs when attempting to mount atapi cdrom Teac CD-540E

[2.] My kernel was compiled with flags

CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_IDEDMA=y
CONFIG_IDEDMA_AUTO=y

My cdrom Teac CD-540E supports UDMA mode2.
When I try to mount /cdrom kernel hangs.
If I invoke

hdparm -d0 /dev/hdc

and invoke "mount /cdrom" after, then everything is OK.

[3.] cdrom, dma, atapi
