I was testing a device driver that I wrote for FreeBSD 2.2.x on a 
FreeBSD 3.0-RELEASE. When some double multiplication and divisions
were executed, the system froze.

It took a long time to find it was a FP problem, it acted like
some aweful infinite loop.

These routines are only used on a circuit setup to calculate some scheduling
parameters, and I guess they can be done with integer math after some head
scratching.

My question is: "Is floating point math now taboo in the kernel?"

--mark.
