Hello,
On a Turris Omnia (Armada 385, Marvell 88E6176) this commit results
in a strange boot behaviour. I see two distinct multi-second freezes
in dmesg. Usually (up to the commit before), the (monolithic) kernel
starts init after ~1.6 seconds, now it takes more than 6....
dmesg output below. Any idea, why this is happening?
Best regards, Klaus
