as a side (spam) note,

I sent a [TECH TOPIC] suggestion to ksummit-discuss a while ago
https://lists.linuxfoundation.org/pipermail/ksummit-discuss/2016-July/002740.html

and a later update
https://lists.linuxfoundation.org/pipermail/ksummit-discuss/2016-September/004006.html

which covers some of the printk problems. so I'm sure I can tell whether
the suggestion has been approved or rejected, but hopefully we can find
some time to sit down and talk about the issues.
