How much additional > testing would be required if we make the new kernel the default? For what its worth our other x86 testing should have largely covered this. If we can't count on the transitive value of our testing using the common fragments/drivers/arch, then we don't have much to count on. I see little risk in this myself, and would support the default changing to linux-yocto in 1.0.1. Acked-by: Bruce Ashfield > > Thanks, > > Darren Hart >
