I also have this problem, except only the brightness up key causes it. The brightness down key does not cause a problem, indeed it actually lowers the brightness of the screen.
I have tried the 3.8.5 and 3.5.0 kernels.
The crash can be triggered at any time after booting the kernel, but the brightness up key works fine in the bios.
