I still have that INVLPG problem on my K5 system.
The symptoms are gcc -pipe and communicator hanging during
compilation/startup (gcc without pipe works!).
Am I the only one who experiences such mysteriously failing
programs on a K5, or is everyone using kernels compiled for
386 on the K5?
When I compile the kernel so that it uses INV instead of INVLPG,
everything works fine. So it's either a bug in how Linux uses
INVLPG, or it is a CPU bug. Since an Intel P5 does not experience
the problem in a similarly equipped system, I suspect the latter.
So if I'm not the only one with that problem, I think it should be
documented at least. Unfortunately I don't have a small test case
which could make it into a runtime check.
So I'd like to get feedback from other K5 owners
if the have similar problems or not, and what kernel configurations
they use.
Tom
