This is a small patch to enable a change of behavior when the INIT# interrupt is received. By including a command line argument 'ia64initpanic', the init_handler_platform will call panic. This is useful because the system is then connected to a call chain and machine restart. The call chain may invoke a netdump or diskdump routine. I think this would be useful for 2.6 as well. Without the cmdline arg, the existing behavior is left unchanged (printing task backtraces to the console and spinning forever). The patch is off 2.4.27 -- Cliff Larsen
