I would also check for a watchdog reset (your 12 msec are close to the
15 msec period for the shortest watchdog reset) - try to disable the
watchdog timer at the start of your program, see page of the
avr-libc-user-manual. But I do not understand why there is a reset but
no significant info in
Although PORF should show something different, I would suspect
glitches in power or on the reset line.. The AVR is very sensitive to
even the shortest blips on reset.
The other thing to check, would be your clock. CKOPT fuse defaulted
with external crystal or resonator is a BAD idea.

I neglected to mention that interrupts are disabled.

I've encountered a problem that I do not understand. Perhaps someone can help
me out.
The problem is the atmega128l is restarting. I've created code that hangs in a
loop and the restart still occurs. The reset status register (MCUCSR) offers
no clue. If I write a null to the register it remains
