I just finished installing FC5 on a machine and now I can't boot itup. The motherboard supports two CPUs, however only one's installed. But for some stupid reason, the installer decided to put only the smp kernel on, instead of both the smp as well as the single (one-up) kernel, so I can't boot the machine now. It locks up during the boot process, doing what appears to be something with CPU1 which doesn't exist. It goes through CPU0 just fine then quits. Does anyone have any suggestions on how to rectify this problem now? The machine does not have a CD drive in it so I can't boot the rescue (or any other) disk.
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 andone 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.

For those curious, I booted it through floppies [1] and did an NFSinstall.
