I'm not on a sandy bridge, but a core2 based lenovo thinkpad (SL410, I 
seem to have this thing fully supported finally...f-keys, sd card etc!). 
I've noticed that BTX halts about 60% of the time for me via DVD. My 
keyboard also does not work at login prompt or elsewhere (during 
fsck...faster!) until after about 2-3 keypresses, after which it's fine. 
BTX via CD/DVD actually seems to work better if i start impatiently 
hitting the keyboard when "-" appears.

I'm not sure if this is a related issue. I also had amd64 btx problems 
on a Dell desktop, so it might be a SATA/scsi/cam timeout thing. Never 
had a problem on server hardware, although most of those boxes were 
Opterons (and thus associated chipsets).

I've come to view FreeBSD dvd boots as a form of gambling.
