Agreed, but I think for starters we should capture the low hanging fruit by calling the shutdown method and then increasingly harden the code by performing less in the kernel that panics and more in the cleanup kernel. That way we can concentrate first on the interfaces to the rest of the kernel. And then we can make the solution bullet proof. > Maybe we could shut down the devices on bringup, then bring it up again > (no I'm not kidding ;-)) ... should reuse the code. Might not be a bad idea. Eric
