What caused that, is > it an in-kernel problem with something? How can it be triggered? In my case I triggered it intentionally. For one of our internal project we want to strictly control the number of drivers/devices allowed in kernel. To verify the feasibility of adding above support, I intentionally failed few bus drivers and checked the behavior. In one of those tests I hence came across the mentioned issue.
In any case, platform bus driver registration failure is a valid case right ? Any issue we notice when this happens needs to be handled right? > > thanks, > > greg k-h >
