A Quick Look at Trap Screens


  • One of the most common questions is "My system trapped" -- what happened?
  • Look at at the module name in MCP/ACP
  • trap 0 may be software or hardware. If all registers are zero except for SS:ESP, it's really a trap 2 -- probably IRQ issue.
  • trap 1 is probably hardware unless maybe you have trace enabled or kernel debugger.
  • trap 3 is probably a DASD driver or JFS. Modname should have come up
