It seems somehwat harmless. During normal operation the variable
fp_thread is NULL (I checked it in  my kernel). But fpintr prints
out that message when it checks to see if fp_thread is NULL, then
it resets the FPU. fpintr should be invoked when the coprocessor
signals an error. And the only sideffect that I see is that this
error will not be reported to any running thread, the FPU
context ist simply reset. This smacks of being broken.
