[gentoo-dev] Kernel problem

[gentoo-dev] Kernel problem

[Clay Mitchell]

I'm getting this problem every time I boot up:

Kernel panic: VFS: unable to mount root fs

Any idea what's causing this? I'm guessing it's a kernel problem - I
copied the one off the rc6-10 build cd and I can boot. But I haven't
been able to track down what is causing this problem.

Any ideas?

This is usually the result of specifying incorrect filesystem parameters
to the boot loader.  Are you keeping in mind the array-like numbering
scheme (012345...) for disk partitions when configuring grub?  Are you 
remembering to turn that logic off and name your root partition as the OS 
understands it for the kernel parameter 'root='?

RE: [gentoo-dev] Kernel problem

[Clay Mitchell]

My /boot directory is /dev/hda1 - it contains both the bzImage and the
menu.lst. The root system is at /dev/hda2

The Grub menu comes up, and I can select a kernel to boot off of, no
problem.

My grub is set up with "root (hd0,0)" and "setup (hd0)")

My menu.lst specifies root as (hd0,0) and

Kernel /boot/bzImage root=/dev/hda2 

Am I missing something?

Nevermind, I did a mrproper and re-config'd everything and now I'm
booting happily

Well, how did you install the kernel that you are having problems with?
You need to compile your own kernel as per the instructions, making sure
to include ReiserFS and ext2 support, Virtual Memory Filesystem support,
and devfs support (*without* the "mount at boot option.)  You will also
need to have support for IDE or SCSI, including disk support.  All these
options need to be *compiled in* to the kernel; they cannot be modules.

[gentoo-dev] kernel problem

[Robert Cole]

 http://forums.gentoo.org/viewtopic.php?t=97254&highlight=agetty+2+6+1 points 
to a problem that I have with all 2.6.1-mm kernels. before 2.6.1 i always ran 
all the -mm kernels with no prob. 2.6.1 vanilla works fine. any solution for 
this prob?

It seems to be a problem with the -mm branch for sure but I've been unable to 
trace the problem because it's not being logged so when I reboot to a known 
good kernel nothing shows up in the logs.

I'd like to get enough info to see if it's just a new setting needed or a bug 
in the kernel that shows up on my hardware. If it's a bug I'd like to get 
enough info about it to report it.

Any help would be appreciated. Thanks!
