Please update the Platform field. 46373 2 georgex.l.musat 2014-10-16 10:33:04 +0000 Hello Darren, The tests for genericx86 are done on a Jetway Atom N2600 board. Our test script builds the rpm and psplash locally and downloads from http://autobuilder.yoctoproject.org/pub/releases/yocto-1.7.rc4/machines/genericx86/core-image-sato-sdk-genericx86.tar.gz for deployment on the board. test-remote-image script is being used to automatically download the required tar.gz file from the root AB link (it goes by itself in <AB Link>/machines/<machine name>/<image type>.tar.gz). Our image type for tests is always core-image-sato-sdk. Thanks. 46379 3 dvhart 2014-10-16 11:48:23 +0000 So, it's very possible the TSC is indeed bad on this platform. Also possible that it has some horrible firmware SMM hack that also yields the TSC to be useless. This, sadly, is not an uncommon problem. 46380 4 dvhart 2014-10-16 11:49:28 +0000 Have you tested this image on another platform? Does it show the same error? 47587 5 georgex.l.musat 2014-12-16 09:39:08 +0000 Hello Darren, I have tested the genericx86 image on jetway and qemu. Only place the error appears is on jetway and I think that there is a problem with the board, as we have all sorts of issues with it and we will replace is as soon as possible. This error does not appear on any other image type or board but jetway. 50598 6 georgex.l.musat 2015-04-29 09:33:07 +0000 We don't test on the jetway any more so marking this as obsolete.
