 Posted: Thu May 26, 2005 7:12 pm Post subject: Kernel panic - not syncing: VFS (SOLVED) |
 |
|
Hi,
seems there are some people still experiencing with the 2.6 kernel.
Maybe somebody has an idea about that:
I cant boot the first time after installation and i get the message:
VFS: Cannot open root device "hda5" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I have one HDD with the following partitions:
/dev/sda1 /mnt/win
/dev/sda2 /boot
/dev/sda5 /
/dev/sda3 /swap
/dev/sda6 /scratch
/dev/sda7 /data
/dev/sda8 /home
my grub.conf essentially looks like that:
root (hd0,1) --> points to /boot
kernel (hd0,1)/kernel-2.6.11-gentoo-r3 root=/dev/sda5
I also used the command line under grub but it gets stuck after "boot"
Any suggestions?

c707176,
This part of your error message means the kernel cannot communicate with your hard drive.
| Code: | | VFS: Cannot open root device "hda5" |
suggests that your grub.conf is not what you think it is.
The root=/dev/sda5 in your posted grub.conf is correct.
Either you do not have /dev/sda5 everythere you should, or the chipset driver for the disk drive is mising from the kernel.

Hi, thanks for your reply!
When I had the 2.4 kernel I compiled with genkernel and I had a statement like real_root=-/dev/hda5 doscsi
since my HDD is recognized as sda.
I changed the boot line kernel now to
kernel /kernel-mykernel root=/dev/sda5
and I get the error:
fsck.ext3: No such device or address while trying to open /dev/hda5
Possibly non-existent couldn't be fixed... |

Ok, I got the solution.
The grub statements are ok but the fstab was wrong.
Instead of /dev/sda there were /dev/hda...
I need to change the fstab and it boots now!
Summarizing: For my problem the following worked
root (hd0,1)
kernel (hd0,1)/kernel-2.6.11-gentoo-r3 root=/dev/sda5 |
