Upgrade kernel

addendum — Fri, 30 Sep 2005 07:03:08 GMT

I hv just upgrade the RH 3 kernel by installing the kernel-xxx binary file , but when reboot to the new kernel , it pop the below messages , it is strange that it is normal when i doing the same thing to another server ( of course they are different hardware ) , could suggest what is the problem ? thx

Your insmod may need updating (the one used by initrd). As you can see, it was unable to load even the first module necessary to eventually access your root file-system.

The new kernel has QUERY_MODULES removed (don't ask why, normally there would be some kind of compatibility-overlap). So, your
older `insmod` or `insmod.static` is trying to use the old-method of loading modules.

You may not be able to recover easily. I found that I needed to rebuild the kernel with the necessary SCSI drivers in the
kernel. This would allow me to boot and mount a root file-system.

Save the previous kernel ".config" file. You must rebuild with the 'loop' device in the kernel as well (or else you can't make a new initrd RAM disk).

Then you can install the new modutils package.

Then you can change back to the previous configuration with `make clean ; make oldconfig`....etc. Rebuild the kernel,
install and boot happy.

what do you have into /etc/modules.conf and what RHEL3 update you install?

Hi,

you could try to append the root= as it says in the diag output and specify the full pathname to the disk /dev/sda1 or if its on cciss /dev/cciss/ccissxxxx,etc..

that may be enough for it to boot, or if you have a recovery floppy boot up to that and then
remount the filesystem as it will be readonly by default, and make the changes to the modules.conf file, then reboot

HTH
