EXPORT(dec_intr_fpu) dec_intr_fpu: PANIC("Unimplemented FPU interrupt handler") I've not encountered this quite yet, but I have an R3K-based DecStation up and running, and if I understand this properly, R3K delivers FPU exceptions as interrupts. It looks like this could take the machine down. Maciej, I was asked to notify you specifically, but this is my only known point of contact. If you could look into this, I would be much obliged. Thanks, Bill
