The MMC I/O errors as detailed in the bug description continue to occur in Vivid. This prevents installation, and also will eventually occur with any intensive write activity, for example if attempting to copy a working system to the eMMC with rsync.
Voyo Minipc, wih Atom CPU Z3735F, and Samsung MCGAFB 64GB eMMC The problem is not present however, in Ubuntu 14.04-2. Can repeatably, successfuly install Lubuntu in this release with none of the errors or messages present in Vivid. So the problem has been introduced since Kernel 3.16.0-30-generic x86_64 #40-14.04.1-Ubuntu. -- 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 ...
