Hi ub3r,
Do you know whether it is locked up due to hardware problem or S/W bug. To segregate this, could you please do following?
1) Not sure if you have this problem with debugger attached on the target. Please Run code using debugger, put breakpoint at the first instruction of user code (just after reset) and run the code.
2) If you still can not debug, please post scope snapshot between VDD/Reset/ISP pin at power on.
