Opened: Dec 09, 2025 Severity: 1-Blocking
After performing a power cycle of active system controller, an error of loading ixgbe diver is observed which results in ctrlplane0x port missing in team0. Errors: [ 5.611594] ixgbe: probe of 0000:06:00.0 failed with error -5
A malformed trunk between the control plane switch and controller host can lead to unpredictably unreliable traffic flows between the controller host and control plane switch.
Install v1.8.X-C/v1.7.C-X build on the system and perform active system controller power cycle. (This is intermittent issue) On the failure case, dmesg logs will point: [ 5.611594] ixgbe: probe of 0000:06:00.0 failed with error -5
Reboot the controller.
None
