User implications:
On cold/warm/fast reboot if there is a syncd service start ongoing, the target procedure will stay blocked until the original call is done. This may delay the action in time.
Why I did it
Improve the upgrade fw script avoiding errors in the logs when cold reboot is executed during service restart
Work item tracking
How I did it
Added locking mechanism for Mellanox FW upgrade
How to verify it
Run cold reboot after DUT first install
