After some debugging, I realized the above is the same issue that this
commit fixed upstream:
commit 71e5f6644fb2f3304fcb310145ded234a37e7cc1
Author: Dietmar Eggemann <dietmar.eggemann@XXX>
Date: Mon Feb 1 10:53:53 2021 +0100
sched/topology: Fix sched_domain_topology_level alloc in
sched_init_numa()
I've backported these fixes and submitted them to stable (5.10.y, 5.4.y
& 4.19.y):
https://www.spinics.net/lists/stable/msg539011.html
https://www.spinics.net/lists/stable/msg539981.html
4.14.y's code is too different for these changes to easily apply.
I'll wait for them to bake there to shake out any regressions before
submitting to Ubuntu. I expect that focal will pick up the fix from
there naturally, but bionic will need an explicit submission since they
won't make it into a 4.14.y release.
