Hi,

At least, 386 + 387/IRQ13, or any IRQ13 coprocessor: From irq.c, IRQ13 calls a lock(), and there is a continous message at an early step of booting, like "lock in interrupt context" if booting SMP.
Anyway last time I seen that, I removed this message by making the lock() only on exception 16 and not in math_error() but there were somewhere another problem, and the kernel can only boot with soft coprocessor - probably not using the hardware one.
I have already reported that few month ago.
