Hi Lars,

Just back from Hol's so will start looking in to this again, we are in the 
process of rebuilding the cluster using Suse 9.1, have already hit
on one snag (which is a specific issue to us and not of DRBD) in that the 
module for our FDDI card (we've got an ancient network) is not
supported - just plain won't work - on a 2.6 kernel , a couple of options 
here. But if we can't get them to work then we will have to go back
to a 2.4 kernel and try the 0.7.4 release......

Will let you know how we get on......

Thanks again

hm. this may have been related to the use of 2.4.x kernel with HIGHMEM.
we had a kernel 2.4+highmem bug fixed with DRBD 0.7.4, so please try 
if you like.

or, of course, use 2.6. kernels, which are what we develop on/for.
