[Bug 1011005] Re: MMC/SD memory card reader stops working after hibernate and resume


Bernie Bernstein, this bug was reported a while ago and there hasn't
been any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your

  MMC/SD memory card reader stops working after hibernate and resume

Status in The Linux Kernel:
Status in “linux” package in Ubuntu:

Bug description:
  On a fresh boot, the MMC/SD memory card reader on my laptop works
  fine.  However, if I hibernate and resume my laptop and attempt to use
  the MMC/SD memory again, the laptop fails to read the memory card and
  I receive a kernel trace from the driver.

  The kernel trace is as follows:
