Thank you for the report! This has been reported and discussed in a few
different places on the mailing list with various solutions:

https://lore.kernel.org/Y7Jal56f6UBh1abE@dev-arch.thelio-3990X/
https://lore.kernel.org/20230102225656.GA3532398@roeck-us.net/

https://lore.kernel.org/20230105031306.1455409-1-masahiroy@kernel.org/
https://lore.kernel.org/20230105132349.384666-1-mpe@ellerman.id.au/
https://lore.kernel.org/CAMj1kXHqQoqoys83nEp=Q6oT68+-GpCuMjfnYK9pMy-X_+jjKw@mail.gmail.com/

For the future, if you are able to bisect to the change that caused the
failure, you can devise a more targeted Cc list and potentially find
some of this information out beforehand, which would allow more threads
to stay together.

The PowerPC build failure that you reported around the same time as this
one has the same root cause.

Cheers,
Nathan
