Ditto on this bug. Infuriating as can be. My computer takes about 15 minutes to start, but it does behave normally _eventually_. Not that we all have time to throw around, but if you turn your Wacom-enabled computer on then take a nice hot shower, it might be working when you return.
I've read on the ArchWiki (https://wiki.archlinux.org/index.php/Wacom_Tablet#System_freeze) that there might be a 'recursive deadlock' condition causing this problem. I skimmed through your bug reference and I'm not sure if it's the same problem.
