[Bug 613880] [NEW] Constant hard drive kernel errors

[Launchpad Bug Tracker]

I have a server running Ubuntu Server 10.4 at home.

After a recent power loss at my home, I tried to SSH into my server but
was unable to.  I hooked it up to a monitor and rebooted, and got an
error message: /dev/mapper/Mustrum-root: UNEXPECTED INCONSISTENCY; RUN
fsck MANUALLY.

I (foolishly) tried to run fsck from my server, with the drive still
mounted, and I ignored the warning.  That didn't resolve my problem.  I
ran fsck from a live CD, and now the above error message does not appear
(instead a friendly /dev/sda1: clean, 204/124496 files, 35686/248832
blocks)

When I start up, shut down, or just leave it for a while (its still
running apache, so I'm guessing some log files keep getting accessed, or
maybe its some other reason), it gives lots of these blocks of
information:

[  xxx.xxxxxx] ata1.00: status: { DRDY ERR }
[  xxx.xxxxxx] ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
[  xxx.xxxxxx] ata1.00: irq_stat 0x40000001
[  xxx.xxxxxx] ata1.00: failed command: READ DMA EXT
[  xxx.xxxxxx] ata1.00: cmd 25/00:08:f0:bf:4b/00:00:20:00:00/e0 tag 0 dma 4096
[  xxx.xxxxxx] ata1.00: res 51/01:00:f0:bf:4b/00:00:20:00:00/e0 Emask 0x1 (device error)

with the x's increasing each line (so the above block repeated several
times), followed by:

end_request: I/O error, dev sda, sector 541835248

I can also get these messages from dmesg
