The bisect is correct. It just has problems to express itself properly. So the table says: | WARNING:at_kernel/time/hrtimer.c:#hrtimer_init | 7 | | | | | BUG:kernel_reboot-without-warning_in_test_stage | 0 | 12 | 6 | 6 | which means _before_ your commit it counted a warning in hrtimer_init() (an unsupported clock id was used). With your commit, the warning was gone and I *think* the userland then printed "BUG:kernel_reboot-without-warning_in_test_stage" because it had no warning. It seems that the bot learned to live with that warning which was around for more than three years. Now that you removed it, it seems to be a mistake to do so because nobody complained about it so far. > Thanks, > > tglx Sebastian
