The NMI watchdog is not deactivated.  Instead there is a kdb state flag
which says to ignore the NMI watchdog tick.  This state bit is twiddled
in several places, it is turned on in main kdb, it is turned off during
a kdb command (to catch loops in commands), it should be turned on
again when waiting for input.  Looks like the state is incorrect.

Which command did you issue that generated "Enter <q> to end, <cr> to
continue:"?
