Bug#818598: src:linux: MTD device probe failed after migrating kernel variant from -orion5x to -marvell
Dear Ian, Martin,
May I know your comment regarding to this armel/orion5x related bug?
I don't know whether qnap also uses MTD to store u-boot related stuff
or not. Just guessing it may have the same issue.
Thank you!
