Thanks for the release. It is much appreciated. So far, I’ve flashed it just fine on several production XO-1’s I have, both on the internal NAND as well as to a 32GB Samsung (Class 6) SD card, however in the case of the SD card install, once the flash completes, and I’m booted into the 13.2.8 environment , I consistently get MMC timeout errors, and the kernel hangs. This is easily reproducible by simply running ‘yum update’ from the CLI. 

The exact message emitted by the kernel is “mmc0: Timeout waiting for hardware interrupt. mmcblk0: error -110 sending stop command, original cmd response 0x900, card status 0xe00.

I can re-boot into the on-board instance of the OS on NAND, and run fsck against the filesystem on the SD card, and no filesystem-level errors are detected there.

Do you have any suggestions for follow-up troubleshooting?
