W11 (compute6 pve-firewall xtables conflicts): race condition between
pve-firewall's iptables_restore (no -w flag) and Docker's iptables
backend. Self-resolves within 10-120s; no firewall gap; no action taken.
Conflicts align to :58 minute mark = Docker daemon start time at last
compute6 boot (Apr 19 12:58).
W12 (compute2 corosync-qdevice boot failures): qnetd on PBS (.153);
PBS has crash-rebooted 34 times since Apr 21, each correlated with USB
ZFS import failure (same as C1, May 5 health check). Each PBS reboot
drops qnetd for ~60s; cluster quorum unaffected (6 node votes, threshold
3). No action this phase. Phase 5 items: fix PBS USB ZFS instability;
optionally migrate qnetd from PBS to Pi4 (.227).
