I'm facing issues with a few Beaglebone blacks getting stuck after working properly for sometime. I'm running the Angstrom image (kernel version 3.8.13+) on these. Each time I see the "task mmcqd/1:74 blocked for more than 60 seconds." message on the debugger. Any pointers on possible causes will be helpful.
