Okay, then I won't track this as a regression; might still be worth
trying a few older kernels in a spare minute to see if it was introduced
in the last 12 or 18 months and can be bisected.
CCed Jiri and Benjamin nevertheless in case they missed this report on
the lists.

I was able to reproduce this bug on kernel 6.6.0 which should rule out a
recent regression. Kernel 6.5.0 refused to start with a modules error.
Going earlier than that is probably pointless given that we are talking
about hardware first released in January 2024.
This issue is also on the kernel.org Bugzilla at: 218836
