Unfortunately this kernel did have the bug. However I have done some testing with the mainline kernels and I have discovered that the bug has been resolved in 4.8.15 (4.8.14 did have the bug) as well as in 4.9-rc6 (4.9-rc5 did have the bug). -- You received this bug notification because you are

This kernel did not have the bug either. BTW are you sure that we are testing the right kernels now? This bisect was supposed to be between v4.7 and v4.8-rc1 but the latest commit you built seems to be from 2016-06-25, which belongs to the 4.7-rc4. ? -- You received this bug notification
