Oooh! This sounds like the problem that others here
just helped me with! I had to disable DMA on my ATA
drive. For me it's an archive store, so I'm not hurt
by it; you may be.
To do this, you have to talk to the boot loader. I
don't recall how the CD-ROM is set up, but if you
get a countdown prompt reading something like
``Booting in 9 seconds. Press <Return> to boot
immediately''
you can hit the space bar (anything but return) to
talk to the boot loader. At that point, you issue
the command
set hw.ata.ata_dma=0
and then
boot
to continue the bootstrap.
After the install, you may have to do this again;
once FreeBSD is up for real, edit the assignment
(without the `set ') into /boot/loader.conf .
If you run this way, you will see interrupt activity
soaking up the CPU during disk transfers; my preferred
monitor is
systat 1 -vmstat
.
