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 ################################## LOG ################################# mpc8313_rdb_setup_arch() arch: exit [ 0.000000] Using MPC8313 RDB machine description [ 0.000000] Linux version 2.6.20 (mess...@localhost.localdomain) (gcc version 4.0.2 20060628 (Wasabi)) #23 PREEMPT Tue Apr 7 10:36:18 IST 209 [ 0.000000] Found MPC83xx PCI host bridge at 0x00000000e0008500.
