> Currently Stop-A (L1A) does not make the kernel switch to OBP on panic.

This is intentional, the kernel prints a message telling the user to
press break (L1-A) if they want to drop out of the kernel and we force
the break to be allowed by setting stop_a_enabled.

I'm wondering why there is so much effort being directed into BRK
behavior.

If you want to break into the OK prompt, have the reboot-cmd
environment variable set appropriately, and simply hit BRK and it will
work in both ldom and non-ldom environments.
