SubjectRe: GRR!! SMP=1 sucks
  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.
