Hi,

just for future reference if someone finds this thread: there is a bit of output I’m seeing with this crashing kernel (unclear whether related to btrfs or not):

OK, an OOM condition is (probably) not BTRFS related FWIW.  IIRC, there 
were a couple of issues with the OOM killer in 4.9, but I don't remember 
specifics.  To be able to determine anything useful though, you'd need a 
lot more context in the kernel logs than just that.
