If you have an i386 system, be sure that it : only had this line. Remove it for all other configurations. Also in FreeBSD/i386 5.0-RELEASE Release Notes: : 2.1.1 Processor/Motherboard Support : [...] : Support for the 80386 processor has been removed from the GENERIC : kernel, as this code seriously pessimizes performance on other : IA32 processors. The I386_CPU kernel option to support the 80386 : processor is now mutually exclusive with support for other IA32 : processors; this should slightly improve performance on the 80386 : due to the elimination of runtime processor type checks. Custom : kernels that will run on the 80386 can still be built by changing : the CPU options in the kernel configuration file to only include : I386_CPU.
