No clue why this happening. It appears the RDTSC instruction is supported by your processor. But for some reason it's not getting to the end of the calibration loop. There's no graceful way out of this loop - some kind of exception must be occurring which is causing E-UAE to abort. Perhaps there is a problem with signal handling? Try running the E-UAE binary from a terminal with gdb. Maybe that will give some clue as to what's going on. Cheers, Rich
