When I change boot args maxcpus=0,the system will not hang up.

The linux kernel version is 3.14.52.

Our platform is Android5.1.1.

How to fix the problem.

Hi jh

this may be caused by ARM or gpu errata, please check that
uboot/include/configs/mx6_common.h for CONFIG_ARM_ERRATA
and for gpu please try latest kernel L4.1.15 where gpu errata
were fixed as described in Table 9 attached Release Notes.

Best regards
igor

The system is hang-up -------When playing video or browse the web, the image stays in a frame, it can't touch, the serial port can't input.

As you said, can we move GPU viv5.0.11p8 into our kernel 3.14.52 that use in Android5.1.1 or Debian ?

Otherwise ,The following log also causes the system to hang-up.
