These messages are expected and are printed via makedumpfile. The
upstream makedumfile project is updated on regular basis to support
newer upstream kernel releases. Until then the above mentioned messages
are printed.
README file included with the makedumpfile source code captures the
kernel version it supports. Currently there is support till 6.11 kernel
[v1.7.6] Update version
Update makedumpfile to version 1.7.6.
This version supports the following new kernels:
- 6.9, 6.10, 6.11 (x86_64)
