My build is a fresh build from git commit id 59833b089e78 ("arm64: improve KTR_TRAP trace entries", 2023-06-24). This is likely a race conditi= on, and I've replicated the failure both on bare metal and VM. The full concatenated log of a root- and user-privileged kyua run is attached, and t= he relevant failure is printed below. sys/net/if_lagg_test:witness -> failed: Lock-order reversals involving if_lagg.c detected [0.078s] The system's behavior doesn't seem too affected by this (as of two hours' uptime in this build), but I figured it's better to report than stay quiet. --=20 You are receiving this mail because: You are the assignee for the bug.=
