I have a persistent issue that I don't even know where to begin to troubleshoot, I've had it on Bluefin since release. If I have a USB keyboard or device plugged in, the grub menu has the standard countdown, if I do not have any USB plugged in it does not have the countdown and will take upwards of 20 minutes to boot. I have upgraded bios, reinstalled truenas and reimported the pools, reset bios to default, Upgraded to 22.12.1, issue persist so I guess its time to report an issue.
