Today I decided to try and get to the bottom of some ext2 corruption I
have noticed under 2.2.12, 2.2.13, 2.3.23, 2.3.24, but not under 2.3.20.
I noticed the first questionable events in the system logs below (first
under light use, and then when ripping a cd.) I am running a AMD
3DII-300 128m RH6.0+ box with two ide drives: hda(FUJITSU MPD3084AT,
8063MB w/512kB Cache, CHS=1027/255/63, UDMA(33)) and hdc(FUJITSU
MPD3043AT, 4125MB w/512kB Cache, CHS=8940/15/63, UDMA(33)) on differnt
ide channels; the CD is on the second ide channel.

To test, I used this nice little command to hammer the ide drives:
[qubes@darklands qubes]$while true; do tar c mp3/ >
/mnt/backup/test.file; md5sum /mnt/backup/test.file; done;

Which seems to work well for large amounts of access. BTW:
/home/qubes/mp3 is on the second drive, and /mnt/backup is a 2gig
partition on the first dirve. More info available on request.
