Two problems remain and seem to be continuing to be unfixed and unacknowledged
in this release despite maintainers previously been cc'd on the problems.

1. Reliably pulling some similar looking oopses on x86_64 when booting up - I
wasn't the only reporter of this. All my traces have complaints about
MAX_STACK_TRACE_ENTRIES too low but I'm not sure if that is the cause of the
trace or happens as a result of the trace.

GRE over IPv4 tunneling driver
NET: Registered protocol family 10
IPv6 over IPv4 tunneling driver
BUG: MAX_STACK_TRACE_ENTRIES too low!
turning off the locking correctness validator.

This too, seems to be going unacknowledged and unfixed. Fair enough, it's new
code but I've received no response as to whether it should work, or shouldn't,
whether I should persist trying with it or if I can help with fixing/testing it
... ?

I had a mysterious hard crash before, immediately preceded by a message about
losing comms to my UPS (serial port) but don't have any further information on
that one, unfortunately.
