Kernek 2.6.30+ compile and boot problem

[zgrw]

Hi all,

I have a Centos5.0 box running on kernel 2.6.18-8.

Well, I need to replace kernel with a newer one. But, when I do compile kernel 2.6.30.5 or 2.6.35, I can't boot it. It gives fallowing errors;

mount: could not find file system '/dev/root'
Setting up other filesystems.
Setting up new root fs
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
Switching to new root and running init.

Well, but if I compile 2.6.18.8 kernel and boot via this one. Everything goes just fine? But, how and why?

I just do this;

-Open tar ball
-Enter directory
-Type "make menuconfig" and use default configure
-Type "make rpm"
-Wait for 2 hours
-type "rpm -ivh ........"
-Change grub
-Boot

Post the contents of grub.conf file here. Are you using UUID or device names assigned to partition(s)?

[zgrw]

well I am using labels; Here is my menu.lst file (legacy grub)

default=0
timeout=3
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
hiddenmenu
serial --unit=0 --speed=19200 --word=8 --parity=no --stop=1
terminal --timeout=3 serial console

title CentOs (2.6.18.8)
	root (hd0,0)
	kernel /boot/vmlinuz-2.6.18.8 ro root=LABEL=/ console=ttyS0,19200n8 console=tty0
	initrd /boot/initrd-2.6.18.8.img

title CentOs (2.6.18-999.lbr5.std.31)
	root (hd0,0)
	kernel /boot/vmlinuz-2.6.18-999.lbr5.std.31 ro root=LABEL=/ console=ttyS0,19200n8 console=tty0
	initrd /boot/initrd-2.6.18-999.lbr5.std.31.img

This works great but 2.6.30.5 doesn't

I found a bug report on redhat.com

bugzilla.redhat.com/show_bug.cgi?id=203696

Now, I am compiling 2.6.27.54 just to try. When it finishes, I will try to boot with that one. I will also publish results here and also if it fails I will post the contents of my initrd image.

2.6.27.54 is also no good; here is initrd;

[root@centos boot]# gzip -dc initrd-2.6.27.54.img | cpio -i --list
