Currently devfs and LVM don't work well together, especially if it is not
mounted on /dev.  My patch fixes a small part of this, but it is still
safer to simply configure devfs out of the kernel when using LVM, until
your system is working properly.

I think this may have been caused by the devfs strangeness.  Start out
with devfs out of the kernel entirely, and go from there.  I don't think
2.4.2 will help you.  You need to apply an LVM kernel patch anyways.

Cheers, Andreas
