hmm, ive not had any issues whatsoever with it.
no notification tray spamming,no suspend issues..
No issues im seeing here in the thread at all.

Only issue I have with ubuntu 12.04 is that whenever I go into suspend mode.. my cooling mat stays running. lol
It used to shut down when the computer went into suspend mode,
but since I installed 12.04, I have to unplug the mat every time or it sucks up battery.
Goes into suspend mode and wakes from suspend fine, it just doesnt kill power to the USB ports.
No probs. with Jupiter though.
