Tell the truth, now. If it's a Pentium II (incl. Celeron), you should have specified "i686", not "i586". D'oh! > I did keep a copy of my old kernel. But, I can't seen to get it to > boot to it. (Yes, this is undocumented. cc'd to -doc) When the boot loader comes up (Press Enter to boot [kernel]), press any key except Enter, and type: unload This will kick your current (defective) kernel out of core, leaving a tabula rasa. Type: load kernel.old This moves your old (pre-3.4-STABLE) kernel into core. Type: boot Self-explanatory. That should bring up your old kernel, but it's no guarantee that this one will work either. So if it doesn't try kernel.GENERIC. If this doesn't work, you may be SOL. Good luck. Once you get your system up and running, immediately modify the kernel config file and recompile--do not pass GO, do not collect $200. Your 3.4-STABLE libraries and system utilities are not meant to work with your 3.x-RELEASE kernel. (Hey, -doc'ers! If this part of the Handbook isn't being re-written by anyone, I'll volunteer to at least write this part (booting an old kernel), if not the entire Build A New Kernel section.)
