 |
|
I Installed a stage 3 tarball optimized for a pentium mmx. I used a vanilla kernel.
On my first boot i get a Kernel panic: VFS: Unable to mount root fs on 03:03 |

Which filesystems did you set up? I've seen this error several times, so you might try a search for Kernel and panic and VFS and Unable and mount and root.

I'd definately take a look at some search results. This has happened at least once before in relation to xfs... perhaps there is an answer.

| I just looked at the search results, but the lot of them are in relation to a gentoo-sources kernel. |

| As far as I know, the vanilla kernel does not have XFS support, so you need to use the xfs-sources or gentoo-sources to get XFS support. That, or you could go to the XFS site and download the kernel patches, but since this is a newbie forum, I recommend unmerging vanilla-sources and emerging gentoo-sources or xfs-sources and recompiling your kernel...all will work then... |

Do I need to edit XFS and gentoo-sources-2.4.19-r8+? Has XFS made it back into gentoo-sources?

I just tried it with gentoo-sources, didn't work 
Next time I'll try xfs-sources |

Hopefully I'm not stating the obvious here, but I'll risk it since I also had a kernel panic after installing. I just had gentoo-sources, ext3 on boot, reiserfs on root, but I don't think any of that matters (at least it didn't in my case). Examine your /boot/grub/menu.lst file. In the line starting with kernel, does it have a /boot/bzImage, or just a /bzImage? Mine had /boot/bzImage, as per the install instructions, but then I had the kernel panic on first boot. I realized that my boot partition had no directory within it called "boot", but rather was mounted as /boot in relation to the root (/) filesystem. So I would try removing the /boot in /boot/bzImage, and give that a whirl (also remove the /boot in the splashimage line).
I wonder if I missed a step in the install instructions, or if there's some assumptions in it that something would happen a certain way while installing. One specific thing: do you guys have a symlink on your boot partition pointing "boot" to "." ? 'cause I don't. 
Hope this helps! |

I believe that /boot should have a self-referential symbolic link in it named boot. (In other words, /boot/boot points to /boot). I'm pretty sure this is installed as part of the initial tar file. Kryptin's point is quite correct if you don't have that symlink, but unless you deleted it (or the install scripts have changed), it should be there - in which case prepending /boot/ to bzImage should have no effect.
I think the points above are about the fact (discussed in various places in these forums, search on XFS and Gentoo-Sources) that the latest build of Gentoo sources no longer includes XFS support (unless that has changed VERY recently). If you have XFS partitions, you need either xfs-sources or you need to patch the vanilla kernel with SGI's patch (available on their website). |

Hrm...yeah...I think I did delete that symlink.  I thought it seemed kinda silly to be able to cd boot forever.... |

One other mistake that can make it so that you are missing the "hall of mirrors" /boot/boot symlink is if you forget to mount your boot partition under /mnt/gentoo/boot before unpacking the stage tarball at install time.
