This is not happening with the kernel 4.16-rc6, so I added the tag kernel-fixed-upstream.
I can no longer boot with the 4.15.0-12 kernel successfully when the error happens, it just freeze and I wait until the HD stops to shutdown it by keeping the power button pressed. I was lucky the system was able to boot and I could obtain some information from the error. Definitively, with the kernel 4.15.0-12 (and previous versions), it has a pattern of: Work -> Don't work -> Work -> Don't work Frequently causing a freeze (kernel panic?). One curious thing I noticed is that it freezes always in the same line on the boot: Started Load/Save Screen Backlight Brightness of backlight:intel_backlight. I don't know why, but it's always on this line. -- 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
