Hi
Why is it not possibly to increse INIT_TASK_SIZE in schred.c and there by increse the kernel stack size?
Im running a heavy loaded RTLinux subsystem and the hole system (2.4.4 from Denx) go's down when i start a big probram in Linux user-space.
Regards

In schred.c? Do you mean include/linux/sched.h instead by any chance?
Because that's the only place where INIT_TASK_SIZE is actually used.
Why do you think you can't increase it?

Um... you don;t want run RTL on a 8xx system; there are a couple of
bugs which have never been fixed - and we (DENX) will not spend any
further efforts on RTL.
Use RTAI instead, which will continue to be supported on 8xx and
other PPC systems.

There are assumptions in the 8xx tlb miss handler that everything above
0x80000000 is kernel space.
