There are multiple cause to this bug. However, patch in attachement may for bug described by Dan Parslow.

[Kernel-packages] [Bug 1422338] Re: I/O errors on mmc partitions
I made some investigations: In some cases system work correctly until it reboot. Applying this patch http://permalink.gmane.org/gmane.linux.kernel.mmc/28281 help in this case. I also find that opening eMMC ith O_SYNC (or mounting partition with "sync" flag) improve results. Finally, I noticed this problem depends on eMMC chip. Samsung eMMC works while ones from Kingstom don't. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1422338 Title: I/O errors on mmc partitions Status in linux package in Ubuntu: Incomplete Bug description: Running live USB of the latest Vivid daily build on Lenovo Thinkpad 10 with Samsung eMMC MDGAGC 116 GiB: Ubuntu 15.04 (vivid-desktop-amd64.iso 2015-02-16 8:05) Linux 3.18.0-13-generic systemd 218-10ubuntu1 Extract of dmesg (full log in attachment): [ 12.337332] mmc0: BKOPS_EN bit is not set [ 12.348788] mmc0: new HS200 MMC card at address 0001 ...
