1. download beagleboard "core-image-sato-sdk" image from http://autobuilder.yoctoproject.org/pub/nightly/20130731-1/machines/beagleboard/
2. boot up a beagleboard xm target
3. execute below commands to test

cd /opt/ltp/testcases/open_posix_testsuite/
make generate-makefiles

4. the make has errors(Segmentation fault). Detail error info, please check below log.

This is a regression issue. When i test it on 20130618-2 image, the test pass.

Comment 1 Saul Wold 2013-08-08 14:52:04 UTC 
Yi, Do you have more than one beagle board or are you seeing this failure and the 4985 on the same hardware?  Can you try a different beagleboard?  This might be a hardware issue.

Hi Saul,
We have 1 beagleboard xM and 2 beagleboard C4. We ran the test on these 2 boards and this issue happened on both of them.

Comment 3 Ning Zhang 2013-08-09 09:41:28 UTC 
Hi Saul,

I've done this test with below scenarios:

1. test 20130731-1 images, kernel is 3.4.52, poky is 9de0ad47462c13ac4a2d73e12e92be6c1b4e0415, test failed.
2. test 20130618-2 images, kernel is 3.4.36, poky is 590010a6525b0e1bc1de73e794764e23404591df, test pass.
3. Use scenario 1 image, downgrade kernel version with scenario 2(cp uImage, MLO files and /lib/modules/ files), which means use 3.4.36 kernel and 3.4.52 rootfs, test pass. 
4. Use scenario 2 image, upgrade kernel version with scenario 1(cp uImage, MLO files and /lib/modules/ files), which means use 3.4.52 kernel and 3.4.36 rootfs, test failed.

I tested all above on a same beagleboard xm target.

So we guess this is not a hardware issue, it is the 3.4.52 kernel issue.
Comment 4 Bruce Ashfield 2013-09-13 04:25:24 UTC 
resolving this, since 3.10 is now the default. We have no cycles
to investigate these on 3.4.
