Hi fellow forum members.

I have my laptop partitioned as follows:
Code: 
[pacija@kaa:/home/pacija]> sudo gpart show
=>        34  1250263661  ada0  GPT  (596G)
          34         128     1  freebsd-boot  (64k)
         162    62914560     2  freebsd-ufs  (30G)
    62914722     8388608     3  freebsd-swap  (4.0G)
    71303330  1178599424     4  freebsd-ufs  (562G)
  1249902754      360941        - free -  (176M)

30G ufs partition is root partition along with /var/, /usr/, /tmp/, and 562G ufs partition is mounted as /home, and it is geli(8) encrypted with AES-XTS 256 and authenticated with HMAC/SHA256.

I just upgraded to 9-STABLE from 9-RELEASE, hoping to resolve my problems with ath(4) wireless driver hangs (system freezes, restarts), and now I see these in my dmesg(8):

Should I be worried?
 
It appears to happen on the same offset everytime. It's possible there's a bad sector at that spot. In that case it's high time to replace the drive.
