Shortly fter reinstalling FC3 yet again, I ran yum --update. After the next boot, my machine froze solid during login. Previously, this had been caused by trying to run an SMP kernel on a hyper-threaded cpu. For some evil reason, the SMP kernel was the default. Whoever made that decision should be shot. Editing grub.conf fixed that problem. Until I ran yum. yum gave me # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,1) # kernel /vmlinuz-version ro root=/dev/hda3 # initrd /initrd-version.img #boot=/dev/hda default=0 timeout=15 splashimage=(hd0,1)/grub/splash.xpm.gz hiddenmenu title Fedora Core (2.6.11-1.27_FC3smp) root (hd0,1) kernel /vmlinuz-2.6.11-1.27_FC3smp ro root=LABEL=/ rhgb quiet initrd /initrd-2.6.11-1.27_FC3smp.img title Fedora Core (2.6.11-1.27_FC3) root (hd0,1) kernel /vmlinuz-2.6.11-1.27_FC3 ro root=LABEL=/ rhgb quiet initrd /initrd-2.6.11-1.27_FC3.img title Fedora Core-up (2.6.9-1.667) root (hd0,1) kernel /vmlinuz-2.6.9-1.667 ro root=LABEL=/ rhgb quiet initrd /initrd-2.6.9-1.667.img title Other rootnoverify (hd0,0) chainloader +1 I suppose I implicitly asked for a kernel update when running yum, but even so, it shouldn't make the default something that doesn't work. That is evil. My guess is that the only reason for vmlinuz-2.6.9-1.667 still being listed is that it was what running when yum ran. In any case, warning: yum can and will replace your grub.conf with one that doesn't work. -- Mike hennebry@xxxxxxxxxxxxxxxxxxxxx "There are three kinds of people, those who can count and those who can't."
