I have a system with an IDE hard disk and CF-IDE adapter.
The CF-IDE adapter works fine with CF cards of 512 MB capacity and less.
As time goes by smaller capacity cards become more difficult to find so
I bought several 1 GB Kingston CF cards.
However these CF cards don't seem to work (on OpenBSD 4.3 stable). I
tried three empty 1 GB Kingston CF cards and they all prevent the system
from getting past loading the kernel.
I went back to a smaller card and then everything is fine.
The error message is
type: ata
c_bcount: 512
c_skip: 0
pciide0:1:0: bus-master DMA error: missing interrupt, status=0x21
This is the dmesg:

Do you think the problem is with the CF cards, with the CF-IDE adapter
or with something in the OpenBSD 4.3 kernel?
