Have not tried M5 yet (still building).  An improved fix was posted for
the PS/2 problem recently which uses a semaphore and work queues rather
than Ingo's original quick fix of just adding a lock-break.  If the
problem is indeed keyboard-related, this may help.

I also have not determined whether the system freezes completely or
whether it is just the input layer that hangs.  Next time this happens I
will try to ssh in.
