Title:
Ubuntu 16.04.4 HWE kernel lockup: Upstream commit missing
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Artful:
Confirmed
Bug description:
I experience random lockups when disabling CPUs, with symptoms very
much as described here:
See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1733662
and when double-checking the source code for 4.13.0-36.40~16.04.1 I can see
that upstream commit d47924417319e3b6a728c0b690f183e75bc2a702 is indeed missing.
