Architecture: pmax
Machine: pmax
>Description:
The pmax secondary bootloader lives at 0x80710000.
The pmax GENERIC kernel is still smaller than this, (_end is at 806a07a8),
but when /boot loads the symbol table for ddb, it overwrites the executing code.
>How-To-Repeat:
Boot pmax GENERIC kernel using pmax bootloader.
>Fix:
Make the kernel the right size again or move the bootloader up further.
