For the record without anyone else in CC: Ha, now I know why I missed that, I forgot to tell regzbot about the bugzilla tickets. To fix this: #regzbot link: https://bugzilla.redhat.com/show_bug.cgi?id=2028613 #regzbot link: https://bugzilla.kernel.org/show_bug.cgi?id=215203 Ciao, Thorsten (wearing his 'Linux kernel regression tracker' hat).
