Yes, you are not alone. 3.6 is giving me "device-mappers missing from kernel?" complaints. Also something about "Incompatible libdevmapper 1.00.19-ioctl (2004-07-03) (compat) and kernel driver"

I see something about it in the "3.6 bugs", here:
http://www.knoppix.net/docs/index.ph...3.6-2004-08-16

in the meantime, I guess I'll try ploping a 3.4 CD in and lilo-ing from there...

Peace, all
