That's 4.5-rc5-ish and the FPU rewrite came during 4.2. BUT!,

58122bf1d856 x86/fpu: Default eagerfpu=on on all CPUs

which is in tip currently, made eagerfpu default and we know that
eagerfpu=off makes the issue go away.

So the bug was there, just it wasn't being hit on Quark. Until
58122bf1d856...
