I had no such behavior on F17 so I don't think it's about my hardware.
BTW, no other Linux distro hangs my box (Debian, Arch) on this specific
HW configuration. So it's about some piece of software maybe kernel or
something specific to F19. Sadly kernel has been updated about 3 times
since I installed F19, so the cause is still there.
