...kage: blktap-dkms Version: 2.0.93-0.1 Severity: serious Justification: fails to build from source (but built successfully in the past) blktap fails to build on kernel 3.13 and probably older kernels as well. According to this bug: https://bugs.launchpad.net/ubuntu/+source/blktap-dkms/+bug/1245009 VM_RESERVED is deprecated as of 3.7. Building with the patch described in that bug allows for blktap to build properly.
