 |
|
Hi, does anyone have some ideas to what the problem can be?
| Quote: | VFS: Cannot open root device "sda3" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available partitions:
kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) |
grub.conf
| Quote: | | kernel /boot/bzImage root=/dev/sda3 |
I have tried to solve it for a while now and did a search and didn't find what I was looking for(maybe I missed it) or maybe I am just too tired at the moment to figure it out, anyways all help are appriciated.

This is the most common problem when manually compiling the kernel.
You are either missing the right controller for your disks in the kernel config or your /dev/sdX has changed.
How many disks do you have?
What is the partition you installed Gentoo on? (Channel 0 or 1) Master or Slave?
You should check also that you have SCSI support in your kernel. For some reasons it is still needed for the SATA controller to work and that SATA disks will be labeled as /deb/sdX
