There is a fuse in the atmega328p that turns the RESET pin into an ordinary I/O pin. Maybe that fuse got changed?

Bit 7 of the high fuse controls this.  It is set correctly to use the pin for RESET function (hfuse = 0xde).

I finally concluded that reset is working.  What isn't working is executing any sketch following reset.

  Because the chip still works some, I think you should overclock, overvolt it until it smokes and see how high it goes!  smiley-evil  You have nothing to lose if you deem it broken.
