Title:
4.15 kernel hard lockup about once a week
Another freeze, end of dmesg below. Given that zram keeps being
mentioned in the error logs, I've now uninstalled zram-config to see if
that helps.

Public bug reported:
My system has been intermittently freezing (from once every couple of
days up to several times a day; absolutely everything appears to be
frozen, only the magic sysrq key works) for the past couple of weeks.
Nothing in particular has changed recently other than updating
