FYI- this discussion is going on in two groups: hackers and bugs. In the interest of not leaving anyone out, I'm sending this only to hackers and cc'ing as appropriate...

It's definitely timing related. The fact that I always do the same thing after the machine boots means I've gotten fast enough to trigger the bug almost every time... :-) Actually, you don't have to be that fast, but being real slow about everything does seem to avoid the problem. [ For simplicity, in the following the VT's start numbering at 1 so they correspond with the function keys.. ] 0. Boot FreeBSD 1. I have VT1 - VT6 with getty login screens, so X appears on VT7 2. CTL-ALT-F5 and login as "archie" on VT5. Start X running. 3. Screen flashes VT1 briefly, then video resets and displays X screen 4. CTL-ALT-F4 to get to VT4 and login as "root" 5. Run command "xwin", which is an alias that pops two root windows up on the X console. 6. CTL-ALT-F7 to get VT7 back to X, ready to happily get to work. 7. Keyboard hangs, screen does NOT switch away from VT4, keyboard leds DO still work, but CTL-ALT-F[1-7] just beeps at me. I'm pretty sure machine responds to pings as well. 8. CTL-ALT-DEL to reboot 9.
