Using the same base image as before, and only updating the kernel: I've
tested upstream builds, starting from the .config found in the Debian
5.16.18-1 package, using oldconfig and accepting everything by default:
- v5.16 is confirmed a first good;
- v5.17-rc1 is confirmed a first bad;
- the culprit seems to be 3ceff4ea07410763d5d4cccd60349bf7691e7e61

upstream.
