In any case, something very veird must be going on.
Thhis is the loop that initializes the track headers, everything except
for the sector numbers:
for (count = 0; count < F_SECT_PER_TRACK; ++count) {
here[count].track = format_req.track;
here[count].head = format_req.head;
here[count].sect = 0;
here[count].size = F_SIZECODE;
}
The unitialized sector is always the first one of the track (not
necessarily the lowest numbered, because of skew...). Other fields (most
notably head) are initialized correctly, and only track seems to have
the value from the previous call.
Weird.
If you suspect a compiler bug, it might be interesting to compile a
kernel on one box, but run it on the other, just to see whether anything
interesting happens...
