problems booting my system..

nunne · Apprentice Joined: 27 May 2004 Posts: 165 Location: Sweden

Installed gentoo on my one and only disk.. /dev/sda...

running fdisk -l on the livecd gets:
/dev/sda1 boot etc.. etc..
/dev/sda2 swap
/dev/sda3 reiserfs

and running fdisk -l in my chrooted env. shows exactly the same...

grub-install and manually installation av grub to hd(0,0) works like a sharm.
and it detects thats its ext2 on /boot.

I get to grub.. but then after awhile i get kernel panic..

Pease provide a real root= (it sais that /dev/sda3 doesn't exist.)
and I have tried /dev/hda3, /dev/hdc3, /dev/sdb3 etc.. and neither workds..

and yes, I have copied /proc/mounts to /etc/mtab.. and it sais /dev/sda3 is / and it's reiserfs.

my grub.conf:

default 0
timeout 5
root (hd0,0)
kernel /kernel-2.6.13-gentoo-r5 root=/dev/sda3

and yeah.. it's amd64.

thanks!

you might have forgotten to enable scsi emulation in the kernel if you did a manual config. if you used genkernel not sure if they include the scsi emulation.

Now you must be thinking, what does scsi drivers have to do with a sata drive? well in linux , sata is emulated by scsi...(long process..kinda hard to explain) so long story short...u have to enable scsi emulation in the kernel somehow

Hi

I have a similar problem on Dual AMD64 with 3ware 9500 SATA raid card.

My grub conf is exactly the same as above and same kernel version.

when i boot, grub starts and I get my selection. when i choose the default i get the following error:

I have the same problem but only on 2.6.14 kernel. If i use 2.6.13-r5 it works fine.

Actually the cause for this is I did not have SCSI emulation compiled into my kernel as standard, it was as module or something.

correct ... i have copied the bzImage from the arch folder to /boot. It borks about the root device not being found, even though I have compiled the 3Ware driver into the kernel.
