I was wrong here, sorry -- the fix for one of the issues discussed in this thread is still just in next as ff8a969f7dc8e7 ("PCI: Skip Target Speed quirk on clamped ports with no link"). >> So if you ask me I think it's overdue someone tests if *vanilla* 7.3 >> (not a vendor kernel) is still affected and reports any remaining >> problems separately anew (e.g. in a new thread) in a way that can be >> read without reading this thread -- while still briefly dropping a >> link >> to this thread for completeness.
