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. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
