Corrupt LVM metadata header after kernel update

I'm running Debian Wheezy (Linux wheezy3.2.0-4-amd64 #1 SMP Debian 3.2.63-2+deb7u1 x86_64 GNU/Linux) as an encrypted LVM with hardware raid 1 (Adaptec 6405E) on a supermicro server. I was encounting the following errors during the the kernel update: Running depmod.

I have an identical machine (same hardware, same partitions, same wheezy installation, same apt sources) running without any problems.
