Cannot load radeon drivers

The following error occurs at genymotion start
libGL error: unable to load driver: radeonsi_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: radeonsi
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

it occurs to in android AVD emulator before applying the following workaround, a bit different now since the folders names changed:
cd $ANDROID_HOME/android-sdk-linux_x86/tools/lib64/libstdc++
$ mv libstdc++.so.6 libstdc++.so.6.bak
$ ln -s /usr/lib64/libstdc++.so.6 $ANDROID_HOME/android-sdk-linux_x86/tools/lib64/libstdc++
seen in here http://stackoverflow.com/questions/36554322/cannot-start-emulator-in-android-studio-2-0

It seems to be something about hardware acceleration since if it is disabled in android AVD emulator the emulator work fine. If is started from the command line with the option -use-system-lib: emulator -use-system-libs -avd YOUR_VIRTUAL_DEVICE_NAME it work too.

A process to replicate the bug is install Ubuntu 16.04.1 LTS, then virtualbox with apt and then install genymotion-2.8.1_x64.bin, at least it was that I used. This way the emulator works. After this if you update the Ubuntu with sudo apt update | sudo apt upgrade the error appears.
