Yes, I berlieve I run the same versions on both occasions. I have only one 
file called lvm-mod.o on my system and that's the one I copied to use with 
the rescue system. I couldn't figure out how to get the version no. from the 
module file, though, just to make sure it's really the same. Tried "insmod 
--verbose" but it didn't give any version no.

On the other hand, your question made me check the kernelversion etc. for the 
rescue system, and it turns out the rescue disk is based on SuSE 5.3 (while I 
use 7.3)  and uses libc5 according to the documentation. That sounds like 
something to do with libraries (even to those not yet initiated, like me, 
into the inner secrets of Linux :-) ). When I have mounted my normal root 
drive on /mnt in the rescue system I link /mnt/lib/* from /lib to be able to 
run the lvm programs. But that only adds the libraries from /mnt/lib. It 
doesn't replace those already there with identical names, if any. Do you 
think the reason could be a mix up of libraries from different versions? Just 
a theory.
