ROUTER CONSOLE MESSAGE NOTIFICATIONS (if any)

ERROR: The system encounters a 'Bus Error' when the processor tries to access
a memory location that either does not exist (indicating a software issue) or does
not respond properly (indicating a hardware issue).
TRY THIS:
1. For 68000 Processor based platforms, carry out the following steps:
   Consider the output:
   "System restarted by bus error at PC 0x30EE546, address 0xBB4C4".
   Here the system is trying to access the address "0xBB4C4"
   a. Based on the address accessed by the router when the 'Bus Error' occurred,
      use the "show region" command to determine the memory location to which
      the address corresponds. If the address reported by the 'Bus Error' does
      not fall within the ranges displayed in the show region output, it implies
      that the router was trying to access an invalid address. This in turn indicates
      a Cisco IOS Software problem. Use the Output Interpreter to decode the output
      of the "show stacks" command to identify the software bug that is causing
      the bus error.
   b. If the address falls within one of the ranges in the "show region" output,
      it implies that the router was accessing a valid memory location, but the
      hardware corresponding to that address did not respond properly. This indicates
      a hardware problem. Find the memory address that the system is trying to
      access (for example in the above output, it is 0xBB4C4), and also the range
      of memory addresses between which this address falls. The hardware issue
      is most likely related to the corresponding component. If a new router has
      been installed, or if the router has been moved from one location to another,
      the memory chips may have become loose. It is recommended that you re-seat
      or firmly push the memory chips into the slot.

2. For the RISC Processor based platforms, use the Output Interpreter Tool to decode
   the output of the "show stacks" command and identify the Cisco IOS Software
   bug that is causing the bus error.

Короче нужен дололнительный вывод нескольких команд.
