DragonFly users List (threaded) for 2006-07
I totally forgot about loader.conf, now the drive gets set to UDMA4 on
boot. Its strange, but mplayer still fails on UDMA4, although I can
mount the dvd no problem. So added the atacontrol command to rc.local.
Im sure the drive can handle UDMA4 since I remember that in Linux this
drive worked perfect in UDMA66 + the manufacturer lists UDMA4 as a
supported mode as well.
I havent been able to replicate the crash yet after a reboot, but if it
happens I'll let you know.

Mine is set to 0. SO I did sysctl hw.ata.atapi_dma=1 and it says:
sysctl: oid 'hw.ata.atapi_dma' is read only
Why is that?
It is a tunable as well, so set it in /boot/loader.conf.
atacontrol has shown me that the device was in PIO4, so I set it to
UDMA4 instead(which is what my drive should be using as it supports it),
but then my dvds couldnt be read so I tried UDMA2 and it improved it
heaps though not perfect, and it seems that mplayer seems to crash more :S.
This is strange... Well, that the drive can't handle UDMA4 is not really
surprising, but you shouldn't see much issues with UDMA2.
*How* does mplayer crash?
