I cannot boot Gentoo without kernel panic. [SOLVED]

[cravengemetzel]

This problem only started occurring in the 3.4.x and 3.5.x kernel series; I used to easily be able to compile working 3.1.x, 3.2.x, and 3.3.x kernels with no issues.

On an otherwise perfect fresh install, I've spent upwards of 24hrs working on recompiling kernel after kernel, troubleshooting, then further recompiling and all to no avail. At first, I was compiling my gentoo kernel manually with the usual "menuconfig" and got the following kernel panic. Not that for the following error messages, I have omitted the timestamps and the rest of the blob following "Call Trace:", for brevity.

Code: Select all

ACPI: [Package] has zero elements (ffff880205b8f8c0)
[drm:i915_init] *ERROR* drm/i915 can't work without intel_agp module!
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Pid: 1, comm: swapper/0 Not tainted 3.4.5-gentoo #1
Call Trace:

The specific snippet, "Unable to mount root fs on unknown-block(0,0)" tells me that either Gentoo doesn't have the necessary filesystem drivers included (I made sure it does, built in-kernel), the proper SCSI drivers, or the proper ATA/PATA drivers. I used both "lspci" and the "inxi" script for Debian to try and determine exactly which drivers I should be compiling into my kernel. The output of these commands will be appended to the end of my post, for convenience.

The partition on which I installed Gentoo from chroot is an ext4 filesystem. I have ext2, ext3, and ext4 built-in to my kernel. There shouldn't be a problem on this front, and also, my "/etc/fstab" is properly configured, with partitions to be mounted designated by UUID.

Some things that I made sure to compile into my kernel, as suggested by the "http://kmuto.jp/debian/hcl/" website for my specific hardware:

Code: Select all

# grep AHCI /usr/src/linux/.config
CONFIG_SATA_AHCI=m
# CONFIG_SATA_AHCI_PLATFORM is not set
# CONFIG_SATA_ACARD_AHCI is not set

Code: Select all

# grep PIIX /usr/src/linux/.config
CONFIG_ATA_PIIX=m
# CONFIG_PATA_OLDPIIX is not set
CONFIG_PATA_MPIIX=m
CONFIG_I2C_PIIX4=m

Unfortunately, this did not help me one bit. In desperation, I compiled genkernel from chroot and made myself a new kernel with "genkernel --menuconfig all". Again, I made sure that the above configurations be included in my kernel. Now, the error message for my genkernel is shorter, and as follows:

Code: Select all

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Pid: 1, comm: swapper/0 Not tainted 3.5.0-gentoo #1
Call Trace:

I am losing hope. Can this problem be fixed? And how? I've compiled many kernels before in my 4 years of Linux experience, but never have been as baffled/exasperated as I am now. My dream is to have a fully working Gentoo system on my laptop, which I paid around $1000 for, specifically to have extreme performance, and thus, pride.

Following are details specific to my hardware. I ran the following commands from my working Debian system; perhaps it might shed some light on what I am doing wrong. Thank you.

For your information. Modules are stored on root partition, in order to load them kernel has to access the root. In your case the modules needed to access the root are stored there. It's like you left the key inside and slammed the door.

Excuse me, but how on earth does this help me, in all it's vagueness ? I RTFM'ed and followed it step by step . In fact, I must have read the manual at least twenty times, from start to finish . Could it be that the manual (which still speaks of the 2.6.x kernel series, no-less), is outdated ?

Would an initramfs solve this issue ?

Code: Select all

CONFIG_SATA_AHCI=m 

You have drivers enabled as modules [m]. They have to be built into kernel image [y]. Sorry, I didn't realize you may be not familiar with kernel configuration.

Ah yes, that makes sense. That was what genkernel produced for me, and so I assumed it was correct. I followed your advice and recompiled my kernel with everything in "Device Drivers -> SCSI Device Support," and "Device Drivers -> Serial ATA and Parallel ATA Device Drivers" as built-in. Still, I get the same kernel panic .

Now, I'm including some "grep" commands which I think might be useful, as I want to avoid posting my entire kernel .config .

Is there anything else I could provide, which may be of use ? Where do I go from here ?

cravengemetzel,

Can we get a look at your grub.conf and fstab files

[Tony0945]

I had to shut AHCI off and use IDE emulation. WD1002FAEX hard drive. The problem might be my Gigabyte motherboard BIOS. Try IDE emulation and see if it boots.

Another idea: boot the system rescue disk and then check with lspci etc to see what's loaded.

cravengemetzel,

Can we get a look at your grub.conf and fstab files

Yes, of course I can provide these configuration files .

Here is the Gentoo section of my GRUB2 /etc/grub.d/40_custom file:

Code: Select all

menuentry "Gentoo Linux" --class gnu-linux --class gnu --class os {
        insmod part_msdos
        insmod ext2
        set root='(hd0,msdos6)'
        search --no-floppy --fs-uuid --set=root 9a5b3da2-17a5-4c5e-838d-94b8377cb1ac
        linux /boot/kernel-3.5.0-genkernel root=UUID=9a5b3da2-17a5-4c5e-838d-94b8377cb1ac ro quiet splash
}

And here is my /etc/fstab file:

Code: Select all

# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed); notail increases performance of ReiserFS (at the expense of storage
# efficiency).  It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.
#

# <fs>                  <mountpoint>    <type>          <opts>          <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.

Since you don't have an initramfs, you can't use UUID's with grub - you have to use the device (/dev). Modify your entry according to mine. I use a symlink for the kernel.

Code: Select all

laptop boot # ls -l
total 4076
lrwxrwxrwx 1 root root      19 Jul 27 23:16 kernel -> kernel-3.3.8-gentoo
-rw-r--r-- 1 root root 4168064 Aug  3 15:11 kernel-3.3.8-gentoo

Code: Select all

menuentry "Gentoo linux gentoo-sources (on /dev/sda7)" --class gnu-linux --class gnu --class os {
	insmod part_msdos
	insmod ext2
	echo	'Setting Linux'
	set root='(hd0,msdos7)'
	echo	'Booting Linux'
	linux /boot/kernel  root=/dev/sda7 rootfstype=ext3 
}

THANK YOU !! I would have never thought that the issue lay within my grub2 configuration ! Now to see if my original (smaller, manually created) kernel will work . Marking this thread as solved . (:
