Then I would really suspect the save/restore code. Saving and restoring floating point state can be very tricky. Do try to find an example in the manual (or possibly in the kernel itself - context switch code) Until this works reliably there is no point in looking for other error sources. You could also try to add code inside the save-resore that destroys all of the floating point registers to be able to spot errors. /RogerL
