Subject: whither patch that fixed K6 32M bug on 2.1.56?
Date: Fri, 30 May 2003 00:12:26 -0400 [thread overview]
Message-ID: <8765ntyswl.fsf@cs.uga.edu> (raw)
Hi. I just bought a computer (cheap!) that appears to have a K6
processor with the bug this website is dedicated to:
http://membres.lycos.fr/poulot/k6bug.html
The problem appears to be a hardware glitch in the K6 where it gets
overly paranoid about self-modifying code. There is a patch at the
above website that changes the 2.1.56 kernel thusly:
Description : If page A is a code page, and A+32MB is a data page,
then the bug can occur. If the memory allocation is modified to
prevent these collisions, the failure rate should decrease
dramatically.
Has anyone done anything with this patch since 2.1.56? I see some
stuff in 2.4.20 that appears to test for the bug and print a warning
that the system may be unstable on detection.
