FreeBSD farm 6.2-STABLE FreeBSD 6.2-STABLE #0: Sun Jul  1 20:56:49 HKT 2007     root at farm:/usr/obj/usr/src/sys/GENERIC  i386
>Description:
I was using a 6.2-STABLE kernel dated before 9-JUN-2007. It was fine. After upgraded the machine today, I could no long boot the machine. It constantly asked me to manually input the device of root file system, which it has detected correctly (i.e. ufs:/dev/ad0s1a).

The problem magically disappeared when I "boot -v" in boot prompt. Could it be a timer issue?

I attached the dmesg of normal boot, and dmesg of "boot -v".

There is no fix but the workaround is:

Then type "boot -v"
