Subject: atapicam - System freeze with hw.ata.atapi_dma=1

Hi All,

I found that issue in older mailings and as bugreport, but its not
mentioned anymore.

Loading atapicam freezes my system, with or without dvdram. Only
solution is setting hw.ata.atapi_dma to 0.

I'd like to see that issue reanimated. Of course i'll give any
information necessary.

I am using an SMP 6.2-PRERELEASE System with a custum Kernel where i
just threw out NICs and some other stuff i dont have.
