The board is a Tyan S2720 2 2.66G Intel Processors 4 Gigabytes of RAM 2 36G ST336607LC Cheetah drives While playing around randomly I found something interesting. If the keyboard is attached while booting, you get the problem I reported before: > Loading /boot/defaults/loader.con > \ But if you boot without a keyboard it gets beyond that point and then pci0: on pci0b Fatal trap 12; page fault while in kernel mode cpuid = 0; apic id = 00 ...a bunch of other stuff. I can't capture this because I can't type fast enough. Also noteworthy, I can't hit "6" to set console to comconsole so that I could cut/paste this. It really seems like there are major problems around the keyboard. (and no such problems with 6.3) -- Jo Rhett Net Consonance : consonant endings by net philanthropy, open source and other randomness
