Ok -- I've gone and re-partitioned my drive (it's now in correct order, and starts with hda2 after main), re-installed Knoppix and... still the same. It was nothing to do my partitions after all. The error message I still get is:

mount: fs type devfs not supported by kernal
I've scanned other posts and checked for bug reports, and it doesn't seem like anyone else is getting this... What could possibly be the problem!? I'm just about ready to give up, and go back to (sigh) Linspire. But I'd really like to get all the packages offered by Knoppix as well as the flexibility.. Anyone else out there with this problem???[/quote]
