From the maintainers' perspective I was thinking mostly of "did 3.10/3.14 seem more troublesome/likely to break than 3.8 when you were writing and testing it?". I take it from your reply that it didn't, and I didn't see any reports of issues in the list archives...so when 2.6.4 is ready I will give it and 3.14 a go. I also saw your tip on the CS5536 boot param and the benchmark results in your other email. Thanks for that, seems to work fine on my system. --Doug Brunner
