Forcing System Memory Dumps

Forcing System Memory Dumps

Because the code to force all CPUs, other than the one that does the dump, to spin is at a very high level, the best way to force a memory dump is to use symmon to call panic with the address of some string in the kernel, as in:

kp call panic addr

On CHALLENGE/Onyx and POWER CHALLENGE/POWER Onyx series systems, an alternative is to use the NMI button.
