x86_64 GNU/Linux)

Unfortunately, I am not experienced at all and I do not understand how to try a
possible fix suggested by CyberCastle at
https://bugzilla.redhat.com/show_bug.cgi?id=596475
Can you please help me - what do I need to do in order to try to fix the
SD card reader problem?
Many thanks!
