we just encountered a very strange bug in SCCM 2012 R2 OSD / ADK. After the migration of our SCCM 2012 infrastructure to 2012 R2 the OSD stopped to work on Lenovo devices (x230, S20, S30, ...). Everytime after applying the image and installing the device drivers the windows 7 minisetup stopped with a bluescreen (0x000000F4). We didn't change drivers or the windows 7 image. All that was different was an updated WinPE to version 5 (incl. ADK 8.1).
We use one single task sequence to deploy x64 and x86 W7-installation. So we have a x86 boot-image in use. After extensive testing over the last few days we can confirm that the BSOD only happens with a x86 boot-image. It doesn't happen with a x64 boot-image. It also didn't help to change/update drivers. It look like DISM is doing something vey strange on those lenovo devices. We also have HP devices but they don't seem to have this problem at all.
Can someone else confirm this? Somehow i can't find any other reports about this and i thought our configuration would be prety common.
