Public bug reported:
Hi guys,
I'm sorry I have no real information to add to this, but Serge
encouraged me to file a bug to get you guys to help me to debug this, so
blame him.
I've been running the bionic kernels on a thinkpad X1 carbon 3rd
generation for several months, and experiencing 2x hard lockups per day.
Nothing in /var/log/kern.log looks very obvious to me, and I'm not lucky
enough to get a stack trace or anything.
Attached are the `ubuntu-bug linux` things that are uploaded
automatically, but I'm happy to do whatever science experiments are
necessary to get further info.
