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: root@imx6qdlsolo:/mnt/src/RVDec/1080# x800_24fps_1940kbps_a_44.1khz_96.5Kbps_2_Transformers2_h1080p.rmvb -rv9_ra6_1920 playbin is employed!
