sata hdd issues, timeouts'n'failures

[Bogdan Webb]

Hi .. i'll be straight to the point, yesterday morning i've experienced some
issues with my FreeBSD 7.2 p7  regarding HDD partition error messages.
It all started a week ago when out of the bloom a few phpBB3 database tables
got corupted and upon reading the messages in /var/log i've saw:
May  3 09:34:36 pgn kernel: ad10: WARNING - WRITE_DMA UDMA ICRC error
(retrying request) LBA=143694719
May  3 09:34:40 pgn kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry
left) LBA=234746399
May  3 09:35:20 pgn kernel: ad10: WARNING - WRITE_DMA UDMA ICRC error
(retrying request) LBA=17996279

May  3 09:35:32 pgn kernel: ad10: TIMEOUT - WRITE_DMA retrying (1 retry
left) LBA=14029855

....a whole bunch of those about 1 minute apart.....

May  3 09:47:09 pgn kernel: swap_pager: indefinite wait buffer: bufobj: 0,

[.............]

until the sistem became very slow and hard to use i've rebooted a few times,
tryed to boot into single user mode and fun fsck but the issues still
occur..
Now the GEOM_LABEL renames the ufsids timeouts still occur, and today ended
up with
May  4 15:26:24 pgn kernel: fsync: giving up on dirty

big issue that it can't wait :( thanks!
