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. --> Steve Wahl On Wed, Mar 06, 2024 at 08:39:38AM +0530, Pavin Joseph wrote: > Hello everyone, > > I tried optimizing the new stable kernel 6.7.8 for space but that did not > resolve the issue. > > pavin@suse-laptop:~> du -s /usr/lib/modules/6.7.8-local/vmlinuz > 10496 /usr/lib/modules/6.7.8-local/vmlinuz > pavin@suse-laptop:~> du -s /usr/lib/modules/6.7.6-1-default/vmlinuz > 14012 /usr/lib/modules/6.7.6-1-default/vmlinuz > > Kind regards, > Pavin Joseph. > > On 3/6/24 01:28, Pavin Joseph wrote: > > On 3/5/24 20:55, Steve Wahl wrote: > > > 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.
