I explicitly am turning it on very early on. Later, I have an

with SPE instructions (e.g.: evstdd) , and there is where the
problems happen. If I explicitly
make sure there are NO SPE instructions in the application, nothing
bad happens!
I am polling the MSR – and it seems the SPE is turned OFF?
What have I done wrong and/or has there been fixes in later kernels
that I should be aware of that might help this issue?
Can you explain what you mean by explicitly am turning it on very
early on.
I can't think of anything that has changed w/regards to SPE handling.
