Customer reported this issue during hardware discovery of 50+ nodes where a few seem to take 15 minutes before actually getting discovered.

The logs provided are in the doxcat code

Looking at the message around this, the only possible code path where we would wait is in the ntp code where we are attempting to sync the clock in the genesis kernel, then sync the hwclock on the server so it will persist on the next reboot.

Creating this issue to track the discussions .
