Hello,
I've setup a new r342378 (December 23) for amd64 onto an external disk
with this procedure:
# grep da0 /var/log/messages
...

# chroot /mnt passwd root

The disk now boots sometimes fine, more times it fails with:
Trying to mount root from ufs:/dev/gpt/extroot [rw, noatime]...
Mounting from ufs:/dev/gpt/extroot failed with error 2; retrying fpr 3 seconds
Mounting from ufs:/dev/gpt/extroot failed with error 2; retrying fpr 2 seconds
Mounting from ufs:/dev/gpt/extroot failed with error 2; retrying fpr 1 seconds
...
I can provide a 'dmesg' output from an successful boot, if this helps.
Any hints? Thanks
matthias
