Thanks for a prompt response. We used the alpha 2 ISO release. I had checked sources.list. The two of us working on this were unaware that there was a difference between non-free-firmware and non-free. non-free-firmware is not mentioned as a component on the debian wiki https://wiki.debian.org/SourcesList <https://wiki.debian.org/SourcesList> But the examples for bookworm show the use of non-free-firmware so it's no wonder we were confused. Could the documentation team amend the wiki to clarify the changes and the differences between non-free and non-free-firmware components? I'm sure this will be a source of confusion moving forward.
In any case, this is a side issue and we await a response from the kernel team in relation to the latency issue with the R8169 module under PREEMPT_RT.
