to summerize

2.4.20-pre5-ac4 works
2.4.20-pre5-ac5 works
2.5.34-mm1 works (without Jens ide port of pre5-ac4)
2.5.34-mm2 fails with unexpected interrupt loop
2.5.34-bk current fails with unexpected interrupt loop

Removing the printk from ide.c does _not_ cure the problem. The ide
setting between 2.4 and 2.5 were as identical as I can make them.

A failing 2.5 boot gives:

Notice that 2.4 orders the boot differently. Wonder if this is significant?

What additional info would help?
