Re: Using 2.6 kernel still unusably slow

[Christopher Calzonetti <ccalzone@xxxxxxxxxxxxxxxxx>]

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.
