Based on some tests, it appears that may help - however it is hard to be conclusive since the behavior is somewhat random, it doesn't fail every time. The first few times I booted this version, I didn't see the problem, but after that it was consistently happening every time until I reverted the patch. Is there potentially a dependency where the PCIe controller doesn't like some other activity that's occurring on the iMX during its initialization sequence? -- Robert Hancock Senior Software Developer SED Systems, a division of Calian Ltd.
