This is funny, but the option btusb.enable_autosuspend=0 make the bug happen on v4.16-rc7. I'm seeing a pattern that, when I change the kernel version or a grub option, I can't just turn on and off the notebook twice (as it triggers normally), but thrice.
So, every time I change a configuration I have to turn the notebook on and off thrice to test. The good new is that btusb.enable_autosuspend=0 triggers the bug. And no v4.15 kernel from mainline is free from this bug. This bug is biting me for a long time and was being very hard to find, but finally it is cornered. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1757218 Title: QCA9377 isn't being recognized sometimes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1757218/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
