Okay, I tried adding the following code to src/base/async/int.c, in the
INT 1A:00 section, right before it checks to see if it should set the flag.
It was the only referance I could find to a midnight flag. It doesn't
seem to help. I guess I need to figure out how the debugging stuff works
for this thing.
/* If the midnight flag is set, it must have already been read, so clear it */
if(*(u_char *) (TICK_OVERFLOW_ADDR)) {
*(u_char *) (TICK_OVERFLOW_ADDR) = 0x0;
}
