Kernel panic
While syncing Primary shows next dump but about a minute before sync starts
we lost the connection with primary.
System is running sarge-backports debian kernel 2.6.15 for i686 with SMP

Is there any kernel compilation requirement to succesfully run drbd???
Servers are connected throught vtund tun tunnel with compression level 9
(zlib) and mtu=1450
People at datacenter tell us that console shows something like:
drdb: sorry ...
kernel panic
not syncing:drdb0: Sorry I have no access to good data anymore
