It sits at the same point I started getting the unexpected interrupt message.
I waited over five minutes to see if the boot would resume.

I have not built any of the recient ac series - been waiting for a reiserfs patch.
Will try 2.4.20-pre5-ac4 and pre6-acx tonight.

No. The boot stalled. The hda stuff is from the dmseg log on a serial
console. The other comments on general info on long standing promise
issues (hopfully fixed in ac).

Realize how anemic this report is. I am willing to get more info on
this - just am not sure what you need or how to get the info. IDE and
the boot sequence is not an area of the kernel I know much about.

Please let me know what would give you the best clues.

Meanwhile I wil try the recient ac(s).
