Hello,
I'm running a 64GB SD card in a CubieBoard2 and getting some errors when
under IO load. My kernel version is:
Linux Cubian 3.14.0-rc2-64776-g6500a8b-dirty #7 SMP Sat Feb 22 03:20:57
UTC 2014 armv7l GNU/Linux
Built form https://github.com/jwrdegoede/linux-sunxi branch sunxi-devel.
I've posted the dmesg output at: http://pastebin.com/rDQpk5yU
The card is almost new and works fine for the same tests in an Intel
laptop. The issue seems occur when running a grep over a large number of
files.
I see some patches posted here recently around MMC issues, but I'm not
sure what is merged where.
MMC stuff is really new and I don't think many people have sd cards that
big. That said, SD cards can be very buggy. I have a 32gb sd card that
doesn't reliably work anywhere, except for my phone. Even via a USB
adapter. So it'll be very hard to debug that one.

Can anyone offer any help?
