This isn't related to -current changes.
The naming scheme of ad0s1a refers to a classic DOS partition table with
a FreeBSD slice as DOS partition 0, and the FreeBSD root partition as
the first (a) partition inside the slice.
ad0a device name stands for a dangerously dedicated disk with no
partition table whatsoever; i.e. it's like doing not "fdisk /dev/ad0 ;
bsdlabel {params} /dev/ad0s1", but going "bsdlabel /dev/ad0" without
creating a DOS-style partition table.
In your case it might mean some data corruption within the partition table.
What does fdisk /dev/ad0 report?
