Hi, all expert,

I run one case on i.MX6q-sabresd board, and found page allocation failure, but the kernel dump show there have free memory, I don't know why does allocate page failed.
Any points or comment are appreciated.

The case:

-          Kernel version: 3.10.53

-          After kernel up,  nfs mount one streaming server, and then aplay the streaming in loop.

-          After 1 hours test,  kernel dump page allocation failure,  but networking and system is active.

-          i.MX6q networking driver:  drivers/net/ethernet/freescale/fec_main.c

The dump log:

Hi, all expert,

I run one case on i.MX6q-sabresd board, and found page allocation failure, but the kernel dump show there have free memory, I don't know why does allocate page failed.
Any points or comment are appreciated.

The case:

-          Board: imx6q sabresd board: 1G ddr memory

-          Kernel version: 3.10.53, with CMA enabled

-          After kernel up,  nfs mount one streaming server, and then aplay the streaming in loop.

-          After 1 hours test,  kernel dump page allocation failure,  but networking and system is active.

-          i.MX6q networking driver:  drivers/net/ethernet/freescale/fec_main.c

The dump log:
