Hi,
don't know whether it's the CDROM drive (a Creative 52x mx) or
the motherboard (ASUS P4S8X) or what.
Anyway, I tried to install a recent version of FreeBSD
(7.1-BETA2) and the installation
hangs right in the boot process of the installation CD disc1.
I see
acd0: FAILURE - READ BIG MEDIUM ERROR asc=0x11 ascq=0x00
run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config
run_interrupt_driven_hooks: still waiting after 120 seconds for xpt_config
run_interrupt_driven_hooks: still waiting after 180 seconds for xpt_config
and so on.
Any clues?

Aloha,
I have had similiar happen on 7 and 8 Freebsd installs recently.
If you install using safe mode it will work. Then in /boot/loader.conf
#boot/loader.conf
hw.ata.ata-dma=0
hw.ata.atapi_dma=0
There is no hw.ata.ata-dma tunable. I think you mean hw.ata.ata_dma
(note: underscore, not hyphen). If you really are using hw.ata.ata-dma,
it does nothing. :-)
Also folks, please remember that "ATA DMA" is for hard disks, and
"ATAPI DMA" is for ATAPI devices (CD/DVD drives).
Error messages from xpt_* functions are from by the ATAPI-to-CAM
emulation layer (think: SCSI emulation for ATAPI devices), but are
likely signs of underlying compatibility problems between the CD/DVD
drive and FreeBSD, and not the fault of atapicam(4).
I'm not sure if there's a loader hint to disable xpt.
The error that comes up when you burn a CD seems to be bogus as I
have used the CD's with out error for installing on other boxes.
The "READ BIG MEDIUM ERROR" often indicates that the CD/DVD drive does
not support a specific read operation mode; some CD/DVD manufacturers
don't implement this command for various reasons.
Aloha Jeremy,
Thanks for catching the - vs _ .
I hear you, but I have to do the hw settings like above or the servers
wont boot they stick at a db>
or mountroot>
Those are two very different things. A db> prompt indicates you're
hitting a kernel panic, while a mountroot> prompt indicates the OS can't
find your root filesystem.
I think the 7 and 8 series OS are looking for SATA and dont like the IDE
drives I use.
I understand, but what I'm saying is that "hw.ata.ata-dma=0" (note the
hyphen) is not fixing/solving anything, because it contains a typo.
I know the atapi setting is for CD's and These are brand new DVD/CD RW
burners fwiw.
A month or so back there were several people on line complaining about
this.
Maybe one of the FreeBSD comitters will have a look and see if
something is wrong.
The "I get dropped to a mountroot prompt" problem has been reported many
times, and so far there haven't been any indications what causes it to
happen for people.

Aloha Jeremy,
The - was not in the installs. I typed it correctly in the several cases
where it was used.
It will be interesting to see if anybody can find a solution to these
issues.
I am not a coder just a long time user of FreeBSD, (since 3.*) I think
it was. It is such a rock solid system that most of us are curious when
something like this happens and its hard to find out why.
