Install CD/DVDs?
more than one person is having problems with kernel panics on startup
due to firewire, and I can't google my way out of this one.
Any advice from the pros?

Tim,
I've got one of the affected motherboards if this is the problem you mean:
http://www.freebsd.org/cgi/query-pr.cgi?pr=136327
The things that have worked for me are disabling firewire in the BIOS
and using a GENERIC kernel or building a kernel with device sbp disabled
and having firewire enabled in the BIOS.
hint.sbp.0.disabled="1" in /boot/device.hints with GENERIC kernel -
still get a panic
sbp_load="YES" in /boot/loader.conf with sbp disabled in the kernel -
get panic.
It seems ok to kldload sbp after the system is up, ie the machine
doesn't panic, but I don't have anything firewire to test with.
Would it be an option to have sbp disabled by default in the install
CD's? Those without the problem can put sbp_load in loader.conf, those
with the problem will have to kldload it later but at least they will be
able to install.
