 Posted: Wed Mar 10, 2010 2:44 pm Post subject: [SOLVED] Kernel panic after changing filesystem |
 |
|
Hi all,
My primary HD died recently (SATA WD RAPTOR 74Go), so I bought a new disk to replace it (SATA SSD Intel X25-M)
I made a fresh reinstall of gentoo, and chosed Ext4 as it seems to be able to support TRIM along with 2.6.33
During install, I compiled a kernel with genkernel, and it works.
After install is done, I tried to compile a custom kernel using my backed up .config that worked perfectly on that computer. As the drive used EXT3, I modified the .config by just adding EXT4 support.
On reboot I get a kernel panic :
| Quote: | VFS: Cannot open root device "sda1" 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)
|
Here are some infos :
grub.conf

Nitro_146,
The error message suggests that the kernel cannot communicate with your SATA controller.
When you used the old .config file, was it from an *identical* kernel version?
If not you must run make oldconfig against it in the kernel tree.
If you have a 32 bit install, ext4 demands that you select huge file support. Its not an option on 64 bit kernels.
From the error, it looks like the kernel did not get as far as trying to talk to the filesystem.
Do you have several SATA controllers in your system and have now connected your new drive to a different one, such that its driver is missing from your kernel?

Thank's for your answer.

Yes, that was the exact same version.

My system is amd64 stable (with multilib)

The disk is connected on the same cable that was used for the previous one, and therefore the same controler (ICH8 as far as I know)

Nitro_146,
So you didn't change anything - it just doesn't work any more. That's a contradiction.
Please post your lspci output and we can take it from there.

There is nothing pluged on the other SATA controler (Jmicron) (The sata ports have different colors on the motherboard)

Nitro_146,
Check your kernel settings against this post check you have the JMicron driver included too.

I just had to remove
| Code: | Device Drivers --->
< > ATA/ATAPI/MFM/RLL support ---> |
After compilation, and reboot, i works !
I am now running that kernel.
Thank you for your help !
