Re: Using 2.6 kernel still unusably slow

Okay. So, I built me a kernel. I used the default options supplied by "make menuconfig" save for I selected a Pentium 4 processor. The "make bzimage modules" part of which took me three hours. :( At least I assume so. I went home and checked the timestamp on the last file it mentioned when I came back this morning.

Hopefully I didn't miss anything:
I did a make modules_install, which created a /lib/modules/2.6.10 directory,
copied System.map to /boot/System.map-2.6.10,
ran mkinitrd /boot/initrd-2.6.10.img 2.6.10,
copied arch/i386/boot/bzimage to /boot/bzimage-2.6.10
edited grub.conf to add the following entry:

title Self built 2.6.10
        root (hd0,0)
        kernel /bzimage-2.6.10 ro root=LABEL=/
        initrd /initrd-2.6.10.img

Anyway, boot time was at best, marginally better. Which I suppose is information, though I don't know what to make of it. :(

I don't have any unusual hardware that I'm aware of, but I've included the output from lspci -v, posted below.

Thanks.

You haven't indicated how or why you have determined that it's a kernel

If you think that's the case, the first thing that I would do is to
custom compile a vanilla kernel 2.6.10 from kernel.org. If you are
unfamiliar with the process, it's really much simpler than it sounds.

On your machine, the process (including setup) should be less than 30
minutes.

Do you have any unusual hardware?

Have you previously posted a lspci -v?
