It is probably best to perform a "Reverse" bisect instead of a standard bisect, since we know this bug is fixed in 4.10 final.
A "Reverse" bisect will identify the commit that fixes the bug instead of identifying the commit that introduced the bug. We just need to do the oppisite of a standard bisect. We need to know the last Bad kernel and the first Good one. Like in comment #28, can you test the following kernels. We are looking for the last bad version and the first good one: v4.5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.5-wily/ v4.7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7/ v4.9: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1667323 Title: Backlight control does not work and there are no entries in /sys/class/backlight To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1667323/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
