Problem:
-----------
Kernel panics and Hardlockup messages when kernel crash was triggered to test
kdump.
There are two patches for a problem during a kernel crash:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=de6e5d38417e6cdb005843db420a2974993d36ff
And:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c0beffc4f4c658fde86d52c837e784326e9cc875
Only the first was marked for stable (and is currently present in
18.04.1), but both should really be included to fix the problems in
the commit log. Can you include the second one, too?
