Pavin, thanks.
For my part, I've loaded OpenSUSE on two different systems but have not succeeded in replicating your problem. I am still working on that.
The systems I have in hand to test this with are Intel, not AMD. Eric Hagberg's report (thanks, Eric!) of seeing it on a PowerEdge R6615 (which also appears to be AMD) suggests to me that AMD systems might have something different, like a different set of commonly included devices on the motherboard, that affects what regions are included in the identity map and makes us trip up here. I will look harder at the logs Pavin supplied to see if I can glean any differences, and maybe see if I can locate an AMD system.

Hello everyone,
I tried optimizing the new stable kernel 6.7.8 for space but that did not resolve the issue.

In the meantime, if you want to try figuring out how to increase the memory allocated for kexec kernel purposes, that might correct the problem.
I tried all the options and variations possible in kexec. Don't know how useful this is but it seems there's a hard limit imposed by kexec on the size of the kernel image, irrespective of the format.
