Beaglebone black getting stuck with "task mmcqd/1:74 blocked for more than 60 seconds." error

[h.work]

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.

Captured logs over serial console:

[79020.491283] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
