Hello, OK, I manage quite a few gentoo systems. ONE of them is being a BIT _ _ ! and I cannot figure out what is obviously simple....
I have already migrated most system that I manage to the 3.2.12 kernel (not testing kernels for me at this time). Background: The system is an old HP AMD dual core laptop: AMD Turion(tm) 64 X2 Mobile Technology TL-56 The error message is this: Root-NFS: no NFS server address VFS: Unable to mount root fs via NFS, try floppy VFS: Cannot open root device "sda4" or unknown block (2,0) Please append a correct "root=" boot option; here are the available partitions: oboo 1048575 sr0 driver:sr Kernel panic - not syncing : VFS : Unable to mount root fs on unknown block(2,0) PID:1,comm : swapper /0 Not tainted 3.2.12-gentoo#2 The other (3) series kernels boot and run just fine: from grub.conf: #0 title= Linux 3.2.1-gentoo root(hd0,1) kernel /boot/kernel-3.2.1-gentoo root=/dev/sda4 #1 title= Linux 3.2.12-gentoo root(hd0,1) kernel /boot/kernel-3.2.12-gentoo root=/dev/sda4 #2 title= Linux 3.0.6-gentoo root(hd0,1) kernel /boot/kernel-3.0.6-gentoo root=/dev/sda4 I can even scp over a kernel from a single processor AMD64 laptop and it boots and runs just fine. When I make a new kernel, I do what I have done for years with Gentoo: cd /usr/src rm linux ln -sf <latest.kernel> linux cd linux make menuconfig <save any changes> make && make models_install cp System.map /boot/System.map-3.2.12-gentoo cp arch/x86_64/boot/bzImage /boot/kernel-3.2.12-gentoo cp .config /boot/config-3.2.12-gentoo So all I can think of is NFS is the difference? I cannot seem to flesh out way the new kernel will not boot on this system and many others are just fine.... maybe I'm missing support for the "sr" driver ? ideas? James
