>From the serial log, it looks to me like you don't have enough memory
reserved. Try bumping up crashkernel=? You're not getting to the point
of running makedumpfile so I don't see how it would be impacted.
Its hard to say why jammy works for you and focal does not. I don't
think we have a larger crashkernel= value by default. It is likely
something more subtle like the initramfs in jammy consuming less memory.
Note that once the memory issue is resolved, I suspect you'll hit bug
1970672.
