Comment(by dsd):

 please enable in your kernel config:

 {{{
 CONFIG_DEBUG_RT_MUTEXES
 CONFIG_DEBUG_SPINLOCK
 CONFIG_DEBUG_MUTEXES
 CONFIG_DEBUG_LOCK_ALLOC
 CONFIG_PROVE_LOCKING
 }}}

 Then when it next hangs, if it doesn't spew anything new automatically,
 run:
 {{{
 echo d > /proc/sysrq-trigger
 }}}
