This isn't a bug in GRUB but a kernel bug that affects older SPARC machines
like your UltraSPARC IIIi. Unfortunately, no one has had the time yet to bisect
this issue.
But since you seem to have a reliable reproducer, you can start trying to bisect
the kernel to find the commit that introduced this regression.
