Ubuntu no longer can read SD Cards (external reader)

[Tommy_CZ]

After upgrade to 16.04, Ubuntu no longer detects SD Cards in my SD Card reader (external -> USB). Before upgrade (from 15.10) it was OK.

Hi, thanks for the cooperation.
I updated BIOS and it partially helped.

1)$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
V22.4
12/21/2015

2) It seems it partially helped, but it is probably because of update in Ubuntu because it was better even before BIOS upgrade. Now, after I plug it into USB, Ubuntu detects it, but after few seconds, it simply dies and it is same as before.

It is a progress, but a little-one.

in USB3, it dies much more quickly (3 seconds), in USB2 after about 10secs.

I can track it in terminal, but I do not know proper commands. If you can tell me them, I can try it ;)

Tommy_CZ, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results.

Thank you for your understanding.
