I left windows and came to Ubuntu for just 1 reason: stable system.
I know I am new to Ubuntu but what I understand about stability is whatever happened in application never should hangs the whole system
so yesterday I was facing issue with VirtualBox so when I run the win7 system I got my real Ubuntu 12.04 system totally hang (no control at all) - I already solved this but I am not happy as I didn't got any solution but just press the power button for like 12 sec. (so any suggestions about what to do when face something like that in Ubuntu?)
Today I noticed that when I came to plug out my USB headphone+mic I got black screen with a lot of statements and nothing to do (any advice?)
One of those statements was:
Kernel panic - not syncing; fatel exception in interrupt
Please advice, and let me know if I need to re-install my ubuntu system as I played a lot in this copy like trying to install all stuff like GNOME, xface, Lubuntu, and so forth.
