Hi,
I am building a custom kernel 2.6.18 on my centOS machine residing on VmWare. I did the following
make clean && make mrproper
make menuconfig
make
make modules_install
After this if i do mkinitrd /boot/initrd-2.6.18 2.6.18-default it is giving out the message
"no modules ata_piix found kernel 2.6.18 aborting."
and stop.
If i neglect it and boot into my new kernel its a PANIC.
Please help.

Thanks

It would seem that your kernel config does not include ata_piix built-in or compiled as a module.

Go back to the 'make menuconfig' step and look for the entry for ata_piix using the search function (/).

You will probably find the option is blank ([ ]).

Configure it as built-in with the "y" key so it looks like this:[*] if you want it to be built into the kernel and not require loading via initrd.

If you wish to load it via initrd then use the "m" key to compile it as a module during build ([m]).

After compilation you should then try again to make the initrd; or if built-in you should just be able to boot without panic (assuming your root filesystem driver is either built-in or a module in the initrd).

ok i will try this. Thank you..

Done, Thank You..
