Hi,
I'am trying to setup drbd with xen in domain-0, synchronisation is
starting but is blocked after some minutes with this kernel message (see
below)
I'am using xen-testing (kernel 2.6.12.6) and drbd-0.7.15.
I'm not able to find out if it is xen or drbd related, but I cannot
reproduce this bug with a vanilla kernel (which works).
Any help would be greatly appreciated,
Lee
