Upgrading to 2.6.5


I am using Red Hat Enterprise Edition 3.0 which comes with 2.4.21-4. I decided to upgrade the kernel to 2.6.5. I downloaded the kernel source and the modutils package. I was able to build the kernel properly and I updated the lilo.conf with the proper files. When I reboot I get a kernel panic and the system says

no such device root=LABEL/ uknown block(0,0)

I changed lilo.conf to show root=/dev/sda1 but I still have the same issue.

Any ideas as to how I can fix this? Appreciate your help.

Did you compile in all the appropriate scsi drivers and root filesystem support?

Also why an old kernel like 2.6.5?

/dev/sda1? So your root file system is on a USB or SCSI device vs IDE? It should probably be /dev/hdaX where X is the partition # if it's an IDE drive. Anyway, did you rerun lilo after modifying the lilo.conf file? And are you sure your new kernel has built in support for the file system you are using on the root partition?

Thanks for your response


Thanks for all your reply. My boot device is /dev/sda1. I think it is a SCSI device. Yes I did run lilo after I edited the file.

Got all the required modules compiled IN to the kernel?
Maybe you could post the result of "grep =y .config" (given in the dir you have the kernel source).
