   The motherboard it is currently on is a new ASUS TX97-E which has specific
support for the K6. The previous motherboard was a "Shuttle HOT-555", which
also has specific support for the K6. The symptoms are the same on both
motherboards: at some random point through a "make world", it will fail
with bizzare errors (like missing semicolon or invalid character). As I said
in a previous message, the chip worked fine for the first 10 or so make worlds
and then began to fail. I've now heard from 5 other people who have had
identical experiance with FreeBSD, and some other people that run Linux
who had a similar experiance. This seems to indicate that there is some
kind of failure mode in the K6 which shows up after a few weeks of use.
I've also heard a rumor that the newest K6 chips don't seem to suffer from
this (yet?).
