CentOS - Jun 2005 - Help rebuilding kernel get mount error on reboot

I am attempting to recompile the kernel with the following steps.

Install kernel-sourcecode rpm

cd /usr/src/linux-2.6.9-11.EL
cp /boot/config-2.6.9-11.EL .config
make menuconfig
       Device Drivers -> Character Devices -> Serial Drivers
        change Max number of non legacy 8250_NR_UARTS to 36
make bzImage
make modules_install
make install

Then after rebooting and selecting my -custom image from the above compile

"mount: error 19 mounting ext3"
"mount: error 2 mounting none"

Then the machine stops of source.

What happended? How do I get my custom kernel to boot.

That is supposed to happen in the "make install".
In fact I looked at /boot and it is there.

THe size of the ramdisk is not even close to the original.
Which since I am using the same config I would have thought it to be the same
size.

initrd.2.6.9-11.ELcustom 307K
initrd.2.6.9-11.EL 390K

Jerry,

The kernel-sourcecode package (it is no-arch) doesn't always apply all
kernel patches for the arch in question.  I actually think it is kind of
worthless and we will probably stop including it.

Try this instead :)

Download the kernel-xxxxx.src.rpm

do:

rpm -Uvh kernel-xxxxx.src.rpm

go to the SPECS directory and do this:

rpmbuild -bp --target i686 kernel-xxx.spec

then go to the BUILD directory and go down to the kernel directory and
build there.

(substitute the versions for xxxxx ... also use the correct --target for
the kernel you are trying to compile)  This will get all the target
related patches applied.

John,

Thanks for the info. I am having trouble with the downloading of the src.rpm.

Is that just on the mirrors somewhere or is there an easy place to grab the
i686.src.rpm?

I tried "rpm -Uvh kernel-2.6.9-11.EL.src.rpm" and got an error.

Where on the mirrors is the i686.src.rpm?

THanks,


Jerry

john,

when installing the src.rpm for the kernel it says bad key ID.

I must have had an incomplete download- I downloaded again and no more error.

Still no go....

I have downloaded the SRC rpm for kernel-2.6.9-11.EL.src.rpm 
<http://mirror.centos.org/centos/4.1/os/SRPMS/kernel-2.6.9-11.EL.src.rpm>
I did rpm -i kernel....src.rpm
cd /usr/src/redhat/SPECS
rpmbuild -bp --target i686 kernel.xxx.src.rpm
cd /usr/src/redhat/BUILD/kernel.XXX/linux.XXX
make bzImage
make modules_install
make install

When I reboot I get the same error about

"mount: error 19 mounting ext3"

Where should I go from here?

Thanks,

Jerry
