Operation not supported by device

[Luciano Mannucci]

Hello!

I'm still migratning servers from linux to FreeBSD. This one I have
added a hard disk, intalled 10.0-RELEASE, mounted linux partitions and
started moving data. Then, while I was waiting, I did a freebsd-update,
rebooted, and now if I try to mount the very same partition I get:

root at vodka:~ # mount -t ext2 /dev/ada1s3 /mnt
mount: /dev/ada1s3: Operation not supported by device

lsvfs says:

root at vodka:~ # lsvfs

ext2fs                           0x000000f3     0  

The partition is ok, I can even fsck it:

root at vodka:~ # e2fsck !:3
e2fsck /dev/ada1s3
e2fsck 1.42.10 (18-May-2014)
/dev/ada1s3: clean, 234263/9445376 files, 2007039/37761485 blocks

What did I wrong?

Luciano.
