Ok, after a lot of time git bisect tell me that the bad commit is a53ee0a308b16e392e0219c585b10f329345766b.
It turns out this commit was reverted yesterday in e2982a04ede454b23ea2f5af11ba4d77d8a70155. My problem is indeed gone in the HEAD kernel. I guess it's a good news but I'm still a bit disappointed to have wasted so much time... ** Changed in: linux (Ubuntu) Status: Incomplete => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1214059 Title: Wifi and bluetooth disabled at boot and hard to re-enable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1214059/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
