Hello All,
I have mpc8313erb with linux kernel 2.6.20.
When I ported the kernel with CONFIG_PREEMPT=y (Enabled) I am getting
the 'scheduling while atomic'. Please check the following call trace,
thanks.
Could anyone please let me to the way to fix it ? ? ?
Kindly please acknowledge ... thank you ...
Kind Regards,
Vijay Nikam
