Bug#319753: linux-image-2.6.12-1-686: Long pause during boot while probing ide

Package: linux-source-2.6.12
Version: 2.6.12-1

Yesterday I experienced a fairly long pause during boot of my Toshiba
Satellite A40 laptop. The pause happens while IDE interfaces are being
probed as indicated in the fragment from kern.log below.
The pause was long enough (about 10-15 seconds) that the first time I
thought the system was hanging completely. Because my old kernel booted
normally, I tried again.
The problem occurred at least 4 times yesterday after both reboots and
cold boots. I've never seen this problem with older kernels.

This morning I cannot reproduce the problem :-P
The difference in the logs is that now the line "ide4: Wait for ready
failed before probe !" is missing.

I'm not quite sure why the kernel is probing for _6_ IDE interfaces as
I'm quite sure the laptop only has 2.
