Description Martin Devon 2008-03-13 20:40:01 UTC 
Running of VIA mini-ITX with 4GB compact flash storage (no HDD) plugged
direct into IDE socket. No cable at all.

FreeBSD presumably fails to find 80 core cable - therefore falls back
incorrectly and unnecessarily to udma33.

How-To-Repeat: Appears in the boot messages each time

Hello Martin, is this still a problem?

Feedback received from Martin: 

Hello Remko 
Yes it is still unsolved. I've updated to FreeBSD 8.0 but it still 
falls back to UDMA33. 
The CF drive plugs in directly to the motherboard socket so there is no 
cable at all

Assign to Mav: would it be possible that you have a look at this please? You might know most about the surrounding ATA code... Thanks!
Comment 4 Alexander Motin freebsd_committer freebsd_triage 2010-07-14 13:23:36 UTC 
Our VIA drivers have no controller-side cable detection and your CF card
 also seems not reporting 80-pin cable. As workaround you may set
hw.ata.ata_dma_check_80pin tunable to 0.

Mav@ gave a workaround, closing as best we can do.
