You are running a -mm kernel, right? There is a bug in there, that
causes this.
Thanks,

Hm yeah, I am, 2.6.9-mm1.
So there's no other way to fix this than changing kernel? Because I
want to keep reiser4-support.

The message is not critical. It just means, that you get (useless) hotplug
events for the class itself which should not happen. This will hopefully
fixed soon in the -mm tree and will go away.

Actually I just commited that change to the main kernel tree, so we need
to fix this up in wait_for_sysfs before we start to get a lot of people
complaining :)

Ok, here is the fix. Bad events with no device in the class are now ignored.
Thanks,
