cannot open root device on (first) reboot on gentoo (kernel 2.6.27)


I'm installing Gentoo on my Thinkpad R61, following the Gentoo installation handbook.
All seems okay until I boot without the livecd, and get kernel panic.

It seems after I boot the system thinks my disks are sda* and cannot find root.

Quote:
vfs: cannot open root device "303" or unknown block(3,3)
please append a correct "root=" boot option; here are the available partitions

0800 sda driver: sd
0801 sda1
0802 sda2
0803 sda3
0b00 sr0 driver: sr
Output from fdisk -l (before boot, of course) says my partitions are hda*.

Quote:
Disk /dev/hda: 120.0GB (etc...)

/dev/hda1 (boot)
/dev/hda2 (swap)
/dev/hda3 (root)
from lspci:
Quote:
IDE interface: intel corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA IDE Controller (rev 03)
I've tried changing lilo.conf to use /dev/sda3, and changed the fstab to say sda*.

Still no luck... Any ideas?

Hi,

welcome to LQ!


You may need to build an initrd with SATA support, but I'm not
a gentoo expert by any stretch of the imagination.



Cheers,
Tink

Thanks for the tip!

How do I do that? I've emerged mkinitrd, but I'm not sure what syntax to use. Reading the man now, but I'm new to this

Solved it.
I had some stupid stuff in my grub.conf (root=/dev/ram0)...

Sorry about that
