After removing atapicam from my kernel, so no panics on boot I decided to s=
ee=20
it DMA was fixed for my CD/DVD combo drive. I changed the=20
hw.ata.atapi_dma=3D"0"
to hw.ata.atapi_dma=3D"1" in my /boot/loader.conf. After a reboot I tried =
to=20
access my cdrom drive, and got the following error messages, which is very=
=20
similar to the messages when trying to dma before ATAng:
Aug 26 22:09:34 littleguy kernel: acd0: WARNING - READ_CD recovered from=20
missing interrupt
Aug 26 22:09:34 littleguy kernel: acd0: WARNING - READ_CD UDMA ICRC error=20
(retrying request)
The problem is that before with DMA enabled it would try dma a few times fa=
il,=20
and then fall back to PIO, whcih though annoying still left the drive in a=
=20
useable condition. Where as now the drive just stays stuck and unusable.
