I have also experienced some of these freezes and system hangs, some of them reproducible, as when I start java+azureus or when xscreensaver pops in. But after I unset CONFIG_DEBUG_RT_MUTEXES they are all gone. Not the DEBUG_RT_MUTEXES has the culpright but judging by the amount of stack traces it spits every few seconds, this workload may potentialize some inner problem in the system. I am currently running rt8 in a FC6 box. I plan to run some further investigation on this matter. Luis | I have a box that looks like it's doing the same thing.
