Hi Greg. Here are three reports for regressions introduced during the 6.9 cycle that were not fixed for 6.9 for one reason or another, but are fixed in mainline now. So they might be good candidates to pick up early for 6.9.y -- or maybe not, not sure. You are the better judge here. I just thought you might wanted to know about them.
* net: Bluetooth: firmware loading problems with older firmware: https://lore.kernel.org/lkml/20240401144424.1714-1-mike@fireburn.co.uk/
Fixed by 958cd6beab693f ("Bluetooth: btusb: Fix the patch for MT7920 the affected to MT7921") – which likely should have gone into 6.9, but did not due to lack of fixes: an stable tags: https://lore.kernel.org/all/CABBYNZK1QWNHpmXUyne1Vmqqvy7csmivL7q7N2Mu=2fmrUV...
* leds/iwlwifi: hangs on boot: https://lore.kernel.org/lkml/30f757e3-73c5-5473-c1f8-328bab98fd7d@candelatec...
Fixed by 3d913719df14c2 ("wifi: iwlwifi: Use request_module_nowait") – not sure if that one is worth it, the regression might be an exotic corner case.
* Ryzen 7840HS CPU single core never boosts to max frequency: https://bugzilla.kernel.org/show_bug.cgi?id=218759
Fixed by bf202e654bfa57 ("cpufreq: amd-pstate: fix the highest frequency issue which limits performance") – which was broken out of a patch-set by the developers to send it in for 6.9, but then was only merged for 6.10 by the maintainer.
Ciao, Thorsten
