I experienced the same issue with my card (also the A-Data 8GB) after
flashing the kernel and rootfs builds from the 22nd.  My partition
table seems to have been deleted.  I'm pretty sure it happened after a
suspend/resume cycle (what happens when you have power management set
to "dim first, then lock").

I had a vfat and an ext3 partition on there that I was using to dual-boot.

Is there a bug report/ticket for this issue I should be adding to?

At the very least, doesn't this belong on the support mailing list
instead of community?
