IMX6Q Yocto Fido Crash on Kernel 3.14.28

adrianmcgrath · ‎11-06-2015

Good afternoon all

I'm running Yocto Fido (v1.8, linux kernel v3.14.28, community BSP) on an i.MX6Q custom board that is similar to the SabreSD. Key differences between SabreSD and custom board are that custom system uses NAND flash for boot and a uSD card for rootfs.

One system suffered a crash last night (log output below). I can see at the head of the logfile that there was a NULL pointer dereference at a virtual address. The crash occurred at: 0x802a42b8 (PC value), using the trace I can see that the crash happens in function:

"debug_smp_processor_id", which was called from:

"rcu_idle_exit", which was called from:

"cpu_startup_entry"

Grepping through the source of linux-3.14.28 I find that:

* debug_smp_processor_id() is in ./lib/smp_processor_id.c;

* rcu_idle_exit() is in ./kernel/rcu/tree.c and

* cpu_startup_entry is in ./kernel/cpu/idle.c

Looking at the source I'm having difficulty tracking down which pointer is the culprit. Any help/suggestions from the knowledgeable folks out there would be greatly appreciated.

Thanks in advance

Adrian

Hi Adrian,

We're experiencing exactly the same situation (Yocto Fido v1.8.1, linux kernel v3.14.28, community BSP) on an i.MX6Q custom board that is similar to the SabreSD, using a uSD card for rootfs). In our case, the i.MX6Q is mounted on a i.MX6 Rex Module Pro by Voipac Tech.

i've tried different "defconfig" kernel configurations, but sooner or later a kernel oops shows up:

Unable to handle kernel paging request at virtual address cd378b37

In fact, this is not the only oops we're seeing, but anyway did you find the culprit of the oops?

Has anybody a workable defconfig file that we could test?

Thanks a lot in advance,

Ángel

Hi Angel

We believe that the issue we were seeing is fixed to one of our dev boards with RAM/NAND hardware issues and are keeping an eye on the situation to see what develops.

In order to assist you, could you tell me:

1) Does the board reach the login prompt or does it always crash during boot?

2) You sort of answered this question in your post, but to clarify, does the crash occur after a consistent amount of uptime or is it totally random?

3) What kind of activities is the board doing during this time (e.g. sat idle, playing videos)?

4) Have you turned off any services to isolate the issue?

5) Do you have any peripherals plugged in?

6) Are there any devices on the board without Linux drivers built in but the pins are still connected in the dts file?

7) Have you run extensive memory tests in Linux/U-Boot to confirm integrity?

8) Do you have any JTAG debug capability available to dump more information from the IMX6?

If you would like to try a recent defconfig of mine, please see the attached file:

Kind regards

Adrian

Hi Adrian

one can check if latest gpu and arm (like ARM Errata 845369) patches are applied,

test with kernel boot parameter maxcpus=1
