  Modified files:
    sys/kern             subr_kdb.c 
  Log:
  Replace critical_enter() and critical_exit() in kdb_trap() with
  intr_disable() and intr_restore() resp. Previously, critical
  regions would have interrupts disabled, but that was changed.
  Consequently, the debugger could run with interrupts enabled.
  This could cause problems for the low-level console code where
  received characters would trigger an interrupt that causes
  the interrupt handler to read the character instead of the
  cngetc() function.
