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?
