I am not using any FP instructions in my code. But while running, my kernel crashes and gives the following panic msg: npx is the Floating point unit (fpu). ---------------------------------- npxintr: npxproc = 0 , currproc = 0, npx_exists = 1 panic: npxintr from nowhere --------------------------------- I am running this code on FreeBSD 4.10. The same code runs fine on FreeBSD 5.2.1, but i want to use FreeBSD 4.10. Has anybody ever got such message or they know the fix for it. I was not able to trace the error...even using kernel debug corefiles. Your help would be highly appreciated. thanks in advance -vaibhave
