OK, based on some searching, here's a new one:
Did a fresh install with 10.6.1 on my 10v, 2GB memory, everything works fine.
Until I hit the F1 key -- then I get the grey circular wheel startup loading screen, but frozen. The screen briefly goes black, then the grey screen comes up; if I hit F1 again, same thing -- black, grey. I can do this multiple times.
The little spinny thing doesn't spin either. I've been looking through the various system logs, and can't see anything terribly obvious. Anyone else seen this?
Bios version is A04. Wake from sleep works okay (legacy USB disabled) as long as I don't close the lid with USB devices attached. Otherwise, everything seems fine.
