I've have a recent problem that has developed on by BBB Rev C+. I'm running Ubuntu 14.04 off SD card. I'm experiencing what appears to be failed access to the SD card. I've attached a console cable and there are no messages there. I do see a message in the kernel log.

Any programs cached in memory can still be used. Anything requiring a read off mmcblk0p2 exhibits this behavior. Is this a failing SD card? To test another one I need to buy one.
