Hi,
It now works with all config parameters set to yes on 2.6.16-rt16.
however, PERCPU_ENOUGH_ROOM is set to 384KB.
I'm now trying to lower this value of PERCPU_ENOUGH_ROOM.
With 256K and 2.6.16-rt16 : doesn't work.
With 320K : OK
So I need to use 320K for PERCPU_ENOUGH_ROOM to boot correctly.
I have several questions :
Is there a problem in my config file ?
Will this memory freed at end of kernel loading ?
Why do we need such a size ?
What usage is this for ?

it didn't work with CONFIG_CRITICAL_IRQSOFF_TIMING set to no and PERCPU_ENOUGH_ROOM = 128K.
