So, guys, please check the latest one.
If the hang up still occurs with this version, then try to define
XXX_SYSTEM_TIMER in sbxfi.c, which is undefined as default.
With this build option, the driver will use the system timer instead
of emu20k1 timer irqs.
If this still doesn't help, try to remove all spinlocks. That is,
just comment out all spin_lock*() and spin_unlock*() calls to avoid
spin deadlocks. Of course, it can be racy, but better than a spin
