[debian-users:52031] [lenny] Buffer I/O error on device sr0
渡辺と申します。
Etch から Lenny へアップグレードしました。
DVD Writer(TS-H653A)で奇妙なエラーが出ます。
Etch では使えていたものが
Lenny では使えないので、困っています。

ところで、
http://cdimage.debian.org/debian-cd/5.0.0-live/amd64/bt-cd/debian-live-500-amd64-gnome-desktop.iso.torrent
を CD-R に焼いて使うと、
関連がありそうなメッセージがブート時に出てました:
sr 4:0:0:0: [sr0] Result: hostbyte=DID_OK drivebyte=DRIVER_SENSE, SUGGEST_OK
sr 4:0:0:0: [sr0] Sense Key : Hardware Error [Current]
sr 4:0:0:0: [sr0] Add. Sense : Timeout on logical unit
end_request: I/O error, dev sr0, sector 1397368
Buffer I/O error on device sr0, logical block 349342
というメッセージがしばらくの間繰り返し出ます。
(一応起動は完了し、使える。だが、めっちゃ動作が遅い)
当方で Lenny で問題になっているのは、今のところ、これだけです。
優秀ですね。
(あ。あと、SVNKit を何とかしないと...)
