I have now installed the kernel image on a server which previously experienced MySQL crashes every 1 to 2 hours. The server uses MySQL for an Icinga2 monitoring database (so it's frequently writing) and is configured to create btrfs snapshots every 5 minutes.
# cat /proc/version
Linux version 4.4.0-22-generic (root@gomeisa) (gcc version 5.3.1 20160413 (Ubuntu 5.3.1-14ubuntu2) ) #40~lp1584052 SMP Fri May 20 14:34:33 UTC 2016

I'll let it run for 24 hours and report back.
