Affected Product(s):
F5OS Velos
Known Affected Versions:
F5OS-A 1.8.3, F5OS-A 1.8.4, F5OS-A 1.8.4-HR1, F5OS-A 1.8.4-HR2
Opened: Apr 30, 2026 Severity: 4-Minor
System event logs on F5OS devices with FPGA show the "firmware update is running" event for the FPGA (e.g., atse 1) with a timestamp that appears before the reboot event, even though the firmware loading actually occurs after the reboot. This can mislead users into thinking the firmware update is the cause of the reboot.
Users may misinterpret the event log, believing the FPGA firmware update is the cause of a random reboot.
Occurs during both physical reboots (power cycling via PSU removal/insertion or AOM) and normal software-initiated reboots. The issue is visible in the "system events" log, but not in the platform.log, where the event order is correct.
Refer to the platform.log for the correct sequence of events; the firmware update event appears after the boot marker in this log.
