Apologies for replying out of order, but I lost the reply (the
downside to running btrfs on my mail server).

I was also suspicious of memory but memtestx86 hasn't found anything
in (though I haven't run it longer than 10min). Sysrescuecd is my
normal rescue image and I haven't gotten that to panic, but I haven't
tried to start any services from it. Unfortunately it is openrc based
so getting systemd running on my btrfs image inside a container will
be painful. Maybe I can find a systemd based rescue image that
includes nspawn.

I suspect I'll have the same issue though as several kernels have failed.

I'll do more extensive RAM tests just in case.  However, the
consistency of the error messages suggests a bug to me.
