: The ATA system in 5.x is known to be broken on several chipsets - see
: http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/60221 for a relevant PR.

My original post stated that this was working on 5.2-R.  This machine was 
also working at various points up to 5.1-R, at 5.1-R, and various points 
from 5.1-R to 5.2-R.  It's just after updating 5.2-R to -CURRENT that it's 
been broken.

The PR (at quick glance) seems to bring up issue with 5.2-RC.  It also
states that PIO4 mode doesn't work.

While my problem is still definitely with ATAng, I'm seeing very different
behaviour, and at different points in the tree, than you.  I can't even boot
in UDMA, but booting in PIO4 works just fine, even in a heavy load -- load
average at about 6, compiling jdk14, X11-4-libraries, and world at the same
time.

That's not to say the issues aren't related, but at first glance, they don't
seem to be.
