[Bug 1422338] [NEW] I/O errors on mmc partitions

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

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):

I get multiple errors when trying to access to mmc partitions:

Ubiquity reports "Input/output errors" consequently, I'm unable to
install Ubuntu on mmcblk0 device.

I don't know if it's related, but I also get a warning from libparted:
