Can you use

SysRq  R E I S U B

to make the reboot softer with your Power PC?

Often but not always, SysRq is on the PrintScreen key (with the alt
key), so it is often described as

alt+SysRq  R E I S U B

See this link

1. Hold down the Alt and SysRq (Print Screen) keys.
2. While holding those down, type the following keys in order, several
seconds apart: REISUB
3. Computer should reboot.
}

Just my two cents
