We have had issues in the past with ibm,os-term initiating shutdown of a partition. This is confusing to the user, especially if panic_timeout is non zero.
The temporary fix was to avoid calling ibm,os-term if a panic_timeout was set and since we set it on every boot we basically never call ibm,os-term.
An extended version of ibm,os-term has since been implemented which gives us the behaviour we want:
"When the platform supports extended ibm,os-term behavior, the return to the RTAS will always occur unless there is a kernel assisted dump active as initiated by an ibm,configure-kernel-dump call."
This patch checks for the ibm,extended-os-term property and calls ibm,os-term if it exists.
