kernel-5.10 started storing kernel (printk) messages in a new lockless ringbuffer. As a result makedumpfile and crash tools are not able to read the kernel log from vmcore 5.10+ kernels. crasdump is important tool for kernel debugging. The log is usually the first thing that people look at. These never kernels are already used in openSUSE Tumbleweek. The needed changes are already upstream. It is just a matter to backport them.
