Hi Carsten,

I tried to disable CONFIG_RT_GROUP_SCHED, but I still got cpu stalls!

Is there a recommended config for the RT patch?

kernel msg attached, it looks like that the stall occurred at the same 
place "menu_select"

Thanks,

Dong

Just a wild guess: Please check your configuration for
CONFIG_RT_GROUP_SCHED=y. Is it there? If so, disable it and try whether
this solves your problem.
