Here is a list of the largest, unsolved mysteries of my system:
1) The back microphone jack on my computer (on my motherboard) does not work
It used to work, but then a couple apt full-upgrades later it didn't. It was the very first thing to break on my system
2) the ALSA sound library has issues and some programs that use it refuse to enable sound, notably Kega Fusion
3) Some flash drives that work fine in windows will have issues transferring files on Siduction. Only NTFS and Fat32 flash drives have been tested
4) My Windows hard disk is no longer editable on siduction, I can't make new files or directories
