When we try to access maintenance mode keeping "M" press the device just stop booting and nothing appears on console. Then if I press the M after some seconds just normal boot. We also try typing "maint" but no luck
Physical or Virtual FW?
It is a very fast and at times subtle timing issue.
You should be seeing a prompt that tells you that you need to press (and not hold) the M, to get it into Maint mode.
