You may have success by adding isolcpus=1 to the kernel command line, which should limit your system to using CPU#0. Alternatively you could boot from floppy, chroot to the installed root and manually add a non-smp kernel from the NFS mounted source with rpm -i. > With past FC versions it always installed two kernels, one smp and > one non-smp so I always had the choice to boot with the single one (then > proceed to remove the smp one since I don't need it.) Apparently FC5 > disagrees with that arrangement. It was recently reported on the list that FC6 will only ship with SMP kernels, since it works fine on (most) uni-processor units.
