I'm making a backup right now, will test once it's done and update this post.
Edit: 9/11 build works fine for me, stock kernel, with (currently optimizing apps) and without gapps (twice). Boot time isn't really bad either, maybe 5 minutes (haven't measured, probably less). Note: I didn't wipe everything, just the caches.
Still having problems with the touch screen not functioning if plugged into usb when booting (even if it's just a charger). Just did a full wipe, will update with more info later, if I don't fall asleep first. lol
~15 minutes later, still stuck at boot. Probably because it was connected to usb, trying again while disconnected.
Still got stuck at boot. This worked for me, though:
1.) full-wipe, flash older aokp (say, 6/25), boot, switch to ART (reboot and let optimize).
2.) flash g-apps, boot and let optimize
3.) wipe cache only, flash 9/11 and g-apps, boot.
Note: I had flashed the BMS kernel at steps 1 and 3, but that should be entirely optional. YMMV
