Hi, I do the same test in qemuarm and 8315E, with 20130731-1 images, no this issue. I also test beagleboard c4 with 20130625-2 image, no this issue neither. So i think this is a beagleboard specific issue. 35533 4 ning.zhang 2013-08-09 09:42:31 +0000 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. 35544 5 bruce.ashfield 2013-08-09 12:49:42 +0000 This is still related to the particular board and it's storage. if this was a general 3.4.52 issue, all boards would be seeing the problem. I'm going to bump 3.4 to 3.4.57 shortly, so it will be worth retesting it there. 36643 6 bruce.ashfield 2013-09-13 04:24:27 +0000 This should be retried on 3.10. 38603 7 bruce.ashfield 2013-11-06 16:33:00 +0000 Has this been retested against 3.10, or are the remaining issues with the beagleboard support preventing that test ? (those other issues should be solved soon). 39819 8 bruce.ashfield 2014-01-15 02:04:39 +0000 I haven't reproduced this, or heard of it on 3.10, so I'm closing the bug as "wontfix".
