最近、ログに次のようなエラーが記録されるようになりました。
これはブートディスク(/dev/sda)のクラッシュの前兆なのでしょうか?
以下のログは、少し長いので恐縮ですが、ご意見を頂ければ幸いです。
よろしくお願いいたします。

最近、ログに次のようなエラーが記録されるようになりました。
これはブートディスク(/dev/sda)のクラッシュの前兆なのでしょうか?
下記のエラーがでており、
1. Kernel側がエンバグした
2. ケーブルが断線しかかっている
3. HDDそのものが壊れかかっている
などが怪しいかと思います。

[ 608.015766] sd 2:0:0:0: [sda] Add. Sense: Unrecovered read error - auto reallocat ...: 1 Time(s)1については、ちょうどカーネルの更新のタイミングとエラーが出始めたタイミングが一致するか、以前のカーネルで起動した場合はエラーがでないか、などを確認することで切り分けられるかと思います。
2,3については、ハードウェアの問題なので、交換するか、PCそのものを買い直すか、となるかと思います。
一応、
sudo smartctl -a /dev/sda sudo smartctl -H /dev/sda
の結果も参考程度に見ておくと良いかもです。

ご返信が遅くなりました。
ご丁寧なアドバイス、感謝いたします。
次のコマンドを実行してみました。
~$ sudo smartctl -l error /dev/sda
smartctl 5.40 2010-07-12 r3124 [i686-pc-linux-gnu] (local build)

(以下、省略)
他方、正常な(そのはず)ディスクに対して同様のコマンドを実行すると、次のようになります。
~$ sudo smartctl -l error /dev/sdb
smartctl 5.40 2010-07-12 r3124 [i686-pc-linux-gnu] (local build)

どうやら、/dev/sdaはかなり危険な状態にあると言わざるを得ないようです。
ちなみに、次のコマンドを実行すると、
~$ sudo smartctl -a /dev/sda
その中の以下の行は「321」を示し、
197 Current_Pending_Sector 0x0012 085 083 000 Old_age Always 321
正常なディスクの場合には、
~$ sudo smartctl -a /dev/sdb
次のようになります。
197 Current_Pending_Sector 0x0022 100 100 000 Old_age Always 0
嗚呼、これはもうディスク異常も確定でしょうか?

どうもそのようですね。
今のうちに救えるデータだけでも救出して、HDD交換なりPC交換なりされるのがよろしいかと思います。

アドバイス、ありがとうございました。
できるだけ早期にディスク交換しようと思います。
まだ、ほんの2年くらいしか使っていないのですが…
オフライン
2年なら経験的には壊れるには少し早い気もしますが、
壊れても不思議は無いとも言える期間ですね。
実際には使い方や環境などにもよると思いますので、なんとも言いがたいところではありますが。。
自分の知識の範囲内では壊れかけているとしか思えないのですが、smartctlでテストを走らせてみるのもよいかもですね。
# あとは、やったことはないので詳細分かりませんが、HDDメーカに保証を求めるとか?
# ものによっては3年くらいの保証期間が付いていたりもするようです。
