    Yes, this is a known issue, errata is in the process of being updated.  Your observations align with ours, in that several different types of SanDisk cards fail, while cards from other manufacturers boot successfully.  For silicon revision 1.0, there is not a robust workaround, other than to continue using the working cards.  We have also seen that if you set both primary and backup to SD card boot, sometimes the backup boot will be successful on certain card that failed the primary boot
