Greetings
I just now finished an upgrade to 8.0 Prerelease vie csup, buildworld,
make kernel (generic), reboot, mergemaster -p, installworld,
mergemaster -Ui, reboot again.

I have a WD external 500G mybook connected via firewire. It has worked
fine since 6.something through 7.x and all of the betas and rc's up to
this point.
I use the drive for backups of all the computers on my network. Booting
into multi-user will fail because the drive is not found. I had to
comment it out of fstab in order to boot multi-user. 
If I unplug the firewire cable I get this message on the console:
Nov 13 12:42:15 asus64 kernel: fwohci0: fwohci_intr_core: BUS reset
Nov 13 12:42:15 asus64 kernel: fwohci0: fwohci_intr_core:

asus64 kernel: firewire0: fw_attach_dev:Removing missing device

Plugging the cable back in gives this:

No device is created in /dev/da*
I did not see anything in /usr/src/UPDATING and I do not recall
anything like this in the mail lists (currect or stable). 
Did I miss something or is this a regression? /var/run/dmesg.boot and
pciconf -lv attached. I can provide anything else needed.
TIA
Robert

I booted with a 8.0RC2 livefs CD and the external disk shows up as /dev/da0, /das1, /das1d. I then connected the external drive via USB and rebooted to the 8.0 Prerelease system. The drive shows up and is able to mount. It appears that some thing is amiss with the latest version. I will download the latest livefs iso and see if that works.
