With the cdrom removed I am getting nice clean boot with no timeouts, errors or lost interrupts:

ACPI was enabled, but disabling it (recompiling with ACPI disabled) does not have any effect.

I am still unable to access the disk on IDE1 even with the cdrom removed on that channel. (though from the dmesg it looks like the cdrom makes things even worse)
I have also tried Alan's new 2.4.21-pre4-ac2 (btw: extraversion is still -ac1), with no difference.
I am looking forward to try the patch!
