Re: HEAD amd64 kernel no boot

["Jeremy C. Reed" <reed%reedmedia.net@localhost>]

Booted amd64 GENERIC head today with boot -v. It hung at:


uhub5 at usb5: vendor 0x1002 EHCI root hub, class 9/0, rev 2.00/1.00, addr1
uhub5: 10 ports with 10 removable, self powered

I waited for a few minutes and pressed CTRL-ALT-ESC.

I ran "next" a few times. It showed a lot of

with some slightly different numbers. Then it started looping like that -- 
many screens full. I pressed space bar and it stopped (no prompt). About 
ten seconds later the laptop powered down.

Any ideas on how I can troubleshoot this?
