The only pentium specific optimizations that are enabled by MPENTIUM4 is to tell the compiler to compile for pentium4 and a few settings in arch/i386/Kconfig. You could enable/disable these individually and see if you can track it down with a binary search. Most of this stuff should be fairly harmless though and be only microoptimizations; I cannot see how they should cause user visible races. -Andi
