    RHEL3 kernel upgrade

    I run a dedicated box with RHEL3 and dual xeons and just ran up2date to install the new kernel they released the other day (also the kernel-source, utils, etc). I am having trouble with the server now, however. When I restarted it and ran top, all I got was 1 CPU, as opposed to 4 (2 physical, 2 virtual (Hyper Threading)).

    Here is grub.conf:
    Code:
    default=1
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Enterprise Linux ES (2.4.21-15.0.2.ELsmp)
        root (hd0,0)
        kernel /vmlinuz-2.4.21-15.0.2.ELsmp ro root=LABEL=/
        initrd /initrd-2.4.21-15.0.2.ELsmp.img
title Red Hat Enterprise Linux ES (2.4.21-15.0.2.EL)
        root (hd0,0)
        kernel /vmlinuz-2.4.21-15.0.2.EL ro root=LABEL=/
        initrd /initrd-2.4.21-15.0.2.EL.img
    Why will it not boot with SMP support?

    Mod edit - changed quote tags to code tags
    If you love something, emerge it

    Well, it's obviously set to boot the UP kernel by default - change default to 0 instead, and it will boot the SMP kernel. It's strange that up2date would have done that though... =/
