(Bug report) the kernel crash when I run cyclictest on DM3730

stanley.miao
Prodigy 25 points

The test command : 

# cyclictest -l100000000 -m -a0 -t1 -n -p99 -i200 -h200 -q
I run the following command to increase cpu's burden at the same time.
# while true; do hackbench; sleep 1;done

cyclictest and hackbench can be get in git://git.kernel.org/pub/scm/linux/kernel/git/clrkwllms/rt-tests.git

The linux kernel version :

the kernel I used is windriver linux kernel. but this bug can also be reproduced on the branch OMAPPSP_03.00.01.06 in git://arago-project.org/git/projects/linux-omap3.git. The kernel in linux-omap-2.6 git tree will hang and didn't give any useful Oops messages when I run this cyclictest.

The Oops messages (it crashed in many different places):

Analysis:

All the kernel crashes occurred at the time when registers were read. These register belongs to prm module, GPTIMER module and 32k sync timer module. All these module are in wakeup domain. I utilize a ICE to debug this problem. And I found all the registers in the wakeup domain cannot be read when the do_DataAbort() was called, whereas the registers in other domains still can be read. 

Taking consider of the wakeup domain is always active and this kernel crashes even when I disabled the CONFIG_PM, I think this problem could probably be a hardware bug. I guess there might be some problem with L4-wakeup interconnect which is used to read registers in wakeup domain.

Hope someone can give me advises to fix this problem or confirm this is a hardware bug.

 

 

Regards.

Stanley.

    Hi,
    

    i think i have the same Error. The problem can be triggert bei using
    

    this command:  cangen can0 -g 100 -I 42A -L 1 -D i -v -v
    

    it sends CAN messages with increment payload every 100ms.
    

    

    !! New info: same bug with:  watch -n 1 echo "test"
    

    

    Kernel from TI am33x git repository (3.1.0) on Beaglebone platform.
    

    After a while the Kernel throws these Ooops:
