[Bug 599601] [NEW] linux-crashdump no output after crash, error in vmcore.log

[Rhomboid]

Public bug reported:

Having random crashes and reboots on previously stable machines. To
troubleshoot, tried installing linux-crashdump but no dumps are
appearing. Occasionally, there is an error message in
/var/crash/vmcore.log, but not consistently:

"open_dump_memory: Can't open the dump memory(/proc/vmcore). No such
file or directory

makedumpfile Failed."

Running apport directly is not possible, machines are not directly
connected to Internet. Will attach output.

** Affects: linux-meta (Ubuntu)
