does your UP kernel have PREEMPT?  in a UP kernel afs builds without
mutexes and this seems like a bad idea in a PREEMPT kernel:

config PREEMPT
        bool "Preemptible Kernel"
        help
          This option reduces the latency of the kernel when reacting to
          real-time or interactive events by allowing a low priority process to
          be preempted even if it is in kernel mode executing a system call.
          This allows applications to run more reliably even when the system is
          under load.

          Say Y here if you are building a kernel for a desktop, embedded
          or real-time system.  Say N if you are unsure.
