Subject:   Unable to mount ext2fs partition

I decided to bump my laptop up to 5.0-CURRENT today.  All seems to have
gone well and all my old binaries work fine, it looks very nice.

However, I can no longer mount my linux partition: when I try, I get
# mount -t ext2fs /dev/ad0s2 /mnt
ext2fs: /dev/ad0s2: No such file or directory

Did something change when I install new bootblocks, and how do I fix it?

Below, output from fdisk and disklabel.  I don't remember anything unusual
before the upgrade.

Thanks,

Rahul
