Subject:   boot hangs with acpi enabled?

Could anyone who is experiencing a boot-time hang on 7-current with acpi
enabled send some information?  First, be sure your system works with
acpi disabled (hint.acpi.0.disabled="1"), otherwise it's something else.

Then, compile your kernel with:
options DDB
options KDB

Reboot with the new kernel and hit CTRL-ALT-ESC when the boot hangs.
Type "trace" to get a stack trace as to what's hung.  Copy down those
lines or take a small photo and send it back.

Thanks,
