While running 2.4.19-pre7-ac2 my system was happily buzzing away.

I upgraded to 2.4.19 and my /dev/hda became /dev/hde which caused various boot problems, which I worked around.

It seems clear that upon booting 2.4.19, the newer kernel recognized the "other" IDE controller on the MB, which 2.4.19-pre7-ac2 had not.

The manual that came with the MB said to use the IDE slots marked IDE0 / IDE1 if I wasn't going to use RAID.

If I wanted to use RAID use the slots marked RAID0/RAID1.

I was just wondering how linux decides which controller is first (hda-hdd) and which is second (hde-hdh).

Here is what I see from dmesg:

For now issue in your append line "ide=reverse".
This will get you by until it can be fixed.

Thanks, that worked.

An interesting note. While things were running backwards, that is on /dev/hde the filesystem was very slow. An operation that generally ran in about 5 seconds took about a minute. A large filesystem backup, generally taking about 5 minutes, took about 45 minutes.

As of reversing things back (/dev/hda) speed is back to normal.

The system only seemed slowed on disk access.
