just compiled GCC 3.0 release (won't bootstrap libstdc++,
but hey), and compiled kernel 2.4.5-ac15 w/ -O3 -march=athlon
The compiled kernel locked when calibrating delay loop
(according to the screen output)
I would guess that it is a problem with the inlining that O3
introduces (seems less likely to be the register renaming,
but what do I know??)
Most likely this is a compiler bug, but it may be gcc, and as
such I am cc:ing to gcc as well as l-k.
