ext3 error

Mar Jul 4 13:33:13 CLT 2006

desde hace tiempo que estoy teniendo este problema... y es que a veces 
derepente la partición del raíz (/dev/hda2) se remonta (remount) en sólo 
escritura... y lo tengo que hacerle un fsck al reinicio.... es muy raro 
porque en otros pcs con linux nunca me había pasado, y hasta ahora ni rtfm ni 
stfw me han servido... a lo único que llego es a fsck, pero la idea es que no 
me vuelva a pasar lo mismo.... aquí adjunto los logs...

antes pasaba bien seguido, pero ahora con el 2.6.17 pensé que el problema se 
había ido pero a las casi dos semanas de uso habitual el problema volvió.

dmesg log:
(al inicio lo que dice del disco duro)
Probing IDE interface ide0...
hda: HITACHI_DK23DA-20B, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Probing IDE interface ide1...

...
(después de que manda el error)

EXT3-fs error (device hda2): ext3_new_block: Allocating block in system zone - 
blocks from 3, length 1
Aborting journal on device hda2.
ext3_abort called.
EXT3-fs error (device hda2): ext3_journal_start_sb: Detected aborted journal
Remounting filesystem read-only
EXT3-fs error (device hda2): ext3_free_blocks: Freeing blocks in system zones

EXT3-fs error (device hda2) in ext3_free_blocks_sb: Journal has aborted
__journal_remove_journal_head: freeing b_committed_data
__journal_remove_journal_head: freeing b_committed_data

Después hice un smartctl -t long /dev/hda, que me dijo que el test terminaría 
en 19 minutos, luego de los cuales hice un smartctl -a /dev/hda
y esto es lo que salió:
