Looks like the bug is related on conflict of the modules rts5139 (card reader) and uvcvideo (webcam). After some googling i've blacklisted the rts5139 module and the webcam is being detected fair. Then I've tested the problem with both modules and mainline kernel 3.15.0-031500rc2-generic #201404201435 SMP. There is definitely a problem - when a card is inserted into card reader, doing some operations on it and eject, close/open the laptop (after sleep mode) the either happens: webcam is disappearing or the entire embedded card- reader disappears. Or, like usually, the webcam is missing right on cold boot. Those problems never happen under 12.04 LTS.
