Colin, sorry to bug you again, but can you tell me if this is the same patch as you applied in your kernel binaries mentioned earlier in the thread? I was running your kernel for a couple days and just had the same Oops occur again. My next step is to take the existing ubuntu kernel, apply just the autofs4 patch you referenced above, and see if that fixes the problem.
