No problem at all.

No please have a close look at the boot sequence of
the 2.5.18 kernel without the above patch applied.
It will:

1. Spew the "Paritition checks" message ony once directly after the
detection of the drive /dev/hda geometry and then never again.

2. It will check the partitions twice, without the above message.

After hot plugging some device the above message should be
perhaps reintroduced, but right now it won't appear at all.

The ideal thing we should do would be:

Detect a channel, detect a disk on a channel, detect partitions on it.

Right now we where doing:
Look for disks, where there are disks, assume there is a channel too.
Look for all disks goemetries.
Look for all disks partitions.

Wuite worng in the context of aproper support for hot
plugging stuff.

So I'm *very* confident about the above change.

What's your problem here - that's the proper thing to do.
