Have paid some attention since your message, to GRUB2 as used in
Kubuntu, that I was installing on a desktop alongside oS-11.2 for
comparative reasons.  This might not be a relevant issue, but just in
case it matters and helps I'll report it here.

Chainloading from oS GRUB "legacy" into Ku's GRUB2 and then booting
oS-11.2's kernel did "work" but resulted in only 1 core being used,
with oS-11.2 really crawling compared to usual (worse than running
single cpu).

oS-11.2 - /boot/grub/menu.list entry :
