 Posted: Fri Apr 14, 2006 1:25 am Post subject: SATA Boot Kernel Panic (VFS: Cannot open root device) |
 |
|
Hi all .. 
This my P4 Gentoo Box ... no other OS is on this box (hope this makes this easier).
Mobo is a Intel 865D
Sata is ICH5
Drive is Maxtor 200gb Sata
Partitions are
/boot /dev/sda1 *
/swap /dev/sda2
/var /dev/sda3
/ /dev/sda4
All is installed ... Kernel is compiled with libata and ICH Sata support built into the kernel.
Here comes the error:
| Code: |
VFS: Cannot open root device "804" or unknown block (8,4)
Please append correct "root =" boot option
KERNEL PANIC
|
I have skimmed through all the other topics in the forum that touch on this error ... but I dont see a definitive answer.
I understand that my Sata device id is 0xD800 so that would make 0xD804 my root partition right?
The part of my lilo.conf that refers to "root ="
is this:
| Code: |
boot = /dev/sda
root = /dev/sda4
|
Its kind of hard to cut n paste screen shots ... since I have to use one my other boxes to search for the answers to my problems.
Thanks in Advance!! |

Wow ... 41 views and no one has a clue?
Come on .. someone must know.
I just recompiled for the 6th time my kernel ... completely from scratch
I see my sata controller load (ICH5)
but for some reason .. its not mapping my sata device properly.
boot = /dev/sda
root = /dev/sda4 <--- that is correct for my lilo.conf
If I only could find out how it is identifying my boot device as (8,4)
At least then I could figure out why I keep seeing the same VFS: Kernel Panic |

I had a similar problem with a 2.6.16-gentoo-r1 kernel recently on 2 PCs. I used IDE drives though. See here.
In one case, compiling the kernel with genkernel and using the initramfs solved the problem. On the other computer I still wait for a solution. |

No need...
I am just going to use GenKernel.
It works.
Seems this was an issue with building my controller into my kernel versus modulizing it and loading it at boot time.
The initramfs method seems to solve my problem .... |

Yep GENKERNEL worked for me .. tho it isn't the solution I want.
It works for now ... eventually I will come across the answer. |

Hey, I just had a problem similar to that one you used to have... I solved it setting the SCSI disk support as built in.
I don't know if you still want to try it out or not, but I really rather to have a manually compiled kernel vs the GenKernel one.
Cheers...

Me too .. which is why this one is bothering me so much.
I think I had all of the scsi stuff .. built in ... but I will double check to be sure.
All in All ... the genkernel at least lets me know that it is possible  |

Old post, still, my solution.
In my case leaving out the :
CONFIG_PARTITION_ADVANCED is not set
did the trick.

|

I had this same issue, after compiling the kernel for my SATA controller I forgot to copy the latest /usr/src/linux/arch/i386/boot/bzImage
to
/boot/kernel-2.6.16-gentoo-r6 (my current kernel version)
After I copied it the system booted with no issues. |
