The rdcpcib driver supports the PCI/ISA bridge and
  watchdog timer as found in RDC's vortex86 and PMX-1000 system on chip. The
  watchdog timer may be configured for expiration periods between one and 512
  seconds.
  - rdcpcib0: watchdog fired bit set, clearing
- A bit was set in the watchdog's timer registers indicating that it has
      reached the configured timeout at last once. This probably means this boot
      has been triggered by a watchdog timeout.
