Internal error: Oops: 17 [#1] PREEMPT

[Deulis]

My first post here!!!

Board: A13-OLinuXino-WIFI
Image: A13_android_NAND_LCD_800x480_EN_second_release

I have "Unable to handle kernel NULL pointer dereference at virtual address 00000008" and "Internal error: Oops: 17 [#1] PREEMPT", the board was working fine, I suspect a hardware failure
Here is this part of the log:

I had a similar problem, on our own design, which was a a hardware problem. Same sd card was running perfectly with other hardware. To localise the problem, i step by step disabled the individual periphery in the script.fex. In my case i found out that the pmu caused the problem.

To locate the error in the kernel source you can use your toolchains addr2line command. In your case get the programm counter value from the kernel message

[    7.270000] pc : [<c01177a0>]    lr : [<c0106dd8>]    psr: 00000013

in your source directory call

arm-linux-gnueabi-addr2line -f -e vmlinux c01177a0

The result will be the file and the line where the error happened
