Hi,
I have a stack hungry code in the kernel. It hits the end of stack from time to time. I wrote function to which I pass pointers to function and memory area which should be used as stack for function execution. (I just load pointer to new stack area into esp register). This function works just fine in user space and memory area provided by me is used as stack.
This function doesn't work in the kernel (system hungs instantly when my function is called). Does antbody have any idea what the reason can be? Some special alignment? Special memory segment? In what direction should I look?
(sure I tried some magic with alignment like - __attribute__ ((aligned (8192))) - no any effect)
(there was some patch to increase stack size kernelwide, but I don't want to affect all the system).
Thanks,
Serge.
