Default 280.11: 100% CPU and hung gnome-session

Symptoms:
1. type username and password at gdm login window
2. gdm login window disappears but nothing happens
3. CPU Fan starts going at max speed

Switching to VT, and using top shows gnome-session is eating 100% CPU.
However perf top shows that all the time is spent in nvidia-driver:

Code:
   PerfTop:    1001 irqs/sec  kernel: 2.5%  exact:  0.0% [1000Hz cycles],  (all, 1 CPU)

                5.00  0.1% 000000000001caa0 symbol_filter          perf

I'm using GNOME3, and it happens logging in as either "gnome-shell mode" or "fallback mode".

EDIT: I forgot to mention that 280.04 works fine.
