FreeBSD 13.2-RELEASE started failing to load i915kms.ko after upgrade from RC5

Hi,

I've been following releng/13.2 since it was branched.
I use amd64 arch for this.

I had built kernel modules during BETA/RC period.
The above i915kms had worked until RC5.
I had not built RC6 locally and picked up RELEASE on releng/13.2.

After upgrading from RC5 to 13.2-RELEASE, the kernel started failing to load i915mks.
This time, all kmod started failing such as one for virtual box, too.

I thought I would need to rebuild all kernel modules, and thus started.
However, even after rebuilding kernel modules several times, i915kms doesn't load properly.
While new virtual box kmod works, I think my build environment isn't a problem.

I cannot make i915kms back in working condition.
I also updated /usr/ports and rebuilt few times but yet not successful.
I get the following error:
```
linker_load_file: /boot/modules/i915kms.ko - unsupported file type
```

Any hints or same experiences?
