Problem is not with mdadm at all, that configured fine. The problem is with init.d script proserver, which is missing LSB headers and thus cannot be ordered due to a circular dependency.
I do not know what proserver, is. But please either fix it by adding LSB headers, or remove/disable it for the upgrade. insserv: warning: script 'S99proserver' missing LSB tags and overrides insserv: warning: script 'proserver' missing LSB tags and overrides insserv: There is a loop between service grub-common and procps if started insserv: loop involving service procps at depth 2 insserv: loop involving service udev at depth 1 insserv: There is a loop at service grub-common if started insserv: Starting proserver depends on grub-common and therefore on system facility `$all' which can not be true!
