SubjectDisk corruption - Abit KT7, 2.2.19+ide patches

Following up on
http://marc.theaimsgroup.com/?l=linux-kernel&m=99889965423508&w=2

Still running the same kernel:

nic@hoppa:/var/log$ uname -a
Linux hoppa 2.2.19 #1 Mon Sep 17 12:56:24 NZST 2001 i686 unknown
nic@hoppa:/var/log$ cat /proc/ide/drivers
ide-cdrom version 4.58
ide-disk version 1.09

New HDD:
nic@hoppa:/var/log$ cat /proc/ide/hda/model
FUJITSU MPG3307AH E

nic@hoppa:/var/log$ sudo hdparm -v /dev/hda

/dev/hda:
multcount = 0 (off)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 3737/255/63, sectors = 60046560, start = 0



I've discovered what seems like some disk corruption.

nic@hoppa:/var/log$ ls -l /var/log/messages
-rw-r----- 1 root adm 996992 Jan 16 08:56 /var/log/messages
is full of:

plus some other binary data.

This Dec 23 entries come 'AFTER' the initial Jan 13 entries at the start of the log.


This rotation of message has been running since:
nic@hoppa:/var/log$ ls -l messages.0
-rw-r----- 1 root adm 185510 Jan 13 06:25 messages.0

message.0 also seems to include corrupted data.


lsof output:

Only things of note running are a distributed net client, samba and
squid cache.

Although for the last three days there has been some higher IO load with
some 100Mb+ files been copied across our WAN via "rsync -vp -aze ssh
{...}".


The Fujitsu drive which replaced the Seagate drive definitely handles
the rough conditions a lot better. Previously the seagate bus would just
lock, and require a hard power reset.


The IDE cables have been replaced, checked to make sure they are
end-to-end installed in each socket. There are NO other IDE devices on
either IDE channel. ie. HDD is only IDE device.


The BIOS on this Abit KT7 is recent as of November when the system had
the hard drive replaced and was last rebooted.




I have another system with much more load, and the same motherboard. Two
HDDs and CDROM and large application load.

It periodic (once a week on average) has a
