Interesting. I can see it merged but then also reverted AFAICT before the 5.19 release. I saw a lot of work around kprint() happened in and after 5.15 so I guess upgrading to 5.15 shouldn’t hurt in any case. Not having a reproducer is the real bummer. I was also wondering whether using other utilities like storing kernel crash dumps on swap would be a good avenue. The only issue here being that this is a KVM/Qemu host with lots of RAM and I think I don’t have enough disk space to capture full system memory dumps … > I'm not being a lot of help here, but hopefully it can lead you > somewhere you can figure this out.

Any pointers where to start and how this relates to potential kprint buffers?
