 From the hardware point of view the only thing which comes to mind is 
that you somehow triggered the ESD protection.

I assume you can rule out an unstable physical connection (because it 
works on windows), so the only thing left is that there is something 
very very badly going wrong with power management.

Have you "tuned" the power tables on the board somehow? Or maybe 
multiple GPUs connected to the same power supply?
