Hi,
I've just moved over to an Opteron 246 dedicated server and have used up2date to install the latest kernel (2.4.21-27.0.4.Elsmp). However, when the machine reboots it never comes back up and according to the datacentre technicians, this is what's happening:
VFS: Cannot open root device"806" or 08:06 Please append a correct "root=" boot option Kernel Panic:VFS:Unable to mount root fs on 08:06
The technician then needs to reboot with the original kernel (2.4.21-27.0.2.Elsmp) to get it to work. Apparently there are no third party modules/drivers loaded. This didn't occur when I did exactly the same thing with a dual Xeon 3.06Ghz machine. Both machines use SATA drives.
Any ideas? Any pointers are greatly appreciated. Incidently, lilo.conf currently looks like this:
prompt timeout=50 default=linux boot=/dev/sda map=/boot/map install=/boot/boot.b message=/boot/message linear
image=/boot/vmlinuz-2.4.21-27.0.4.ELsmp label=newlinux initrd=/boot/initrd-2.4.21-27.0.4.ELsmp.img read-only root=/dev/sda6 image=/boot/vmlinuz-2.4.21-27.0.4.EL label=2.4.21-27.0.4.E initrd=/boot/initrd-2.4.21-27.0.4.EL.img read-only root=/dev/sda6 image=/boot/vmlinuz-2.4.21-27.0.2.ELsmp label=linux initrd=/boot/initrd-2.4.21-27.0.2.ELsmp.img read-only root=/dev/sda6
