Comment 9 for bug 1556602

The suggested workaround in https://bugs.launchpad.net/ubuntu/+source/lvm2/+bug/1556602/comments/8 did not work for me. What did work however was to build a modified lvm2 package using the aforementioned patch, then boot from external media, install the modified lvm2 on the externally booted ubuntu, then mount the system's main fs using the modified lvm, then install the modified lvm2 again this time on the system's fs using chroot.

This process is cumbersome and I wish ubuntu would include this patch by default.
