Hi, I just applied the patch, recompiled,... here's the deal:
drbd0: sock was shut down by peer
drbd0: meta connection shut down by peer.
drbd0: short read expecting header on sock: r=0
drbd0: asender terminated
drbd0: worker terminated
drbd0: Connection lost.
drbd0: Discarding network configuration.
drbd0: receiver terminated
drbd0: worker terminated
drbd0: ASSERT( mdev->ee_vacant==0 )

By the way, how do I get the latest version out of cvs ?
cvs -z9 checkout -r rel-0_7-branch doesn't seem to work.
