Jenkins el7 slaves are running 5 months old kernel missing security updates and features causing CQ failures.
due to features expected to work at cpu level and enabled only by a mix of kernel and microcode_ctl updates.
Please update and reboot all slaves.
CQ failures are not caused by the kernel version, nevertheless I've upgraded all bare metals attached to the production Jenkins instance.
do we have a playbook to replace existing el7 VMs with fresh ones? I’d like to try that out instead of spending time upgrading existing ones.
