 i386

>Description:
I'm running NetBSD 5.0_RC1 on a Dell Latitude CPi.  When booting
from cold using a GENERIC kernel, (almost) everything's fine.  If
I reboot (for instance by "shutdown -r now"), though, the kernel
hangs after printing a few lines.  I don't have this problem if I
disable ACPI using the "-2" boot option, though that seems to cause
other problems.

The install CD suggests I send dmesg output, so here it is.  I've marked
the line where it hangs on a warm boot.

>How-To-Repeat:
Boot NetBSD 5.0_RC1 CD on a Latitude CPi.  Exit to a shell; run "reboot".
The second boot will fail.
