You will be in the new kernel (confirm with uname -a= , it will show you the build date and git hash). 5) Perform some test like your iperf. 6) If the performance is good: cd /usr/src git bisect good Repeat step 3 & 4 7) If the performance is bad: cd /usr/src git bisect bad Repeat step 3 & 4 8) Keep repeating steps 3 through 7. After a handful of repetitions, you w= ill run out of commits to test and it will spit out the first bad hash. Post t= hat here. 9) To restore your system to a desired kernel, say 12.4 with security patch= es: git checkout releng/12.2 Repeat step 3 & 4 --=20 You are receiving this mail because: You are the assignee for the bug.=
