Copy the live cd kernel to your machine and make it an option in grub |
| 30 |
and try booting that. Then at least you can stop chrooting and |
| 31 |
optical mounting. This will give us some information on if it is a |
| 32 |
kernel problem or not. Make sure to make modules_install |
| 33 |
|
| 34 |
If it's the kernel, check out kccmp to compare the kernel options |
| 35 |
between Live CD and the machine's kernel configuration after you dig |
| 36 |
up the configuration for the kernel on the Live CD. |
| 37 |

Other people are mentioning udev, and I wonder about this, too. |
| 39 |
Either before or after you check the kernel (whichever you decide is |
| 40 |
easier or seems better to you), can you chroot and rebuild udev |
| 41 |
through portage and also run a revdep-rebuild please? You said you |
| 42 |
updated, but it is not clear to me that the full update was proper. |
| 43 |
If you don't have revdep-rebuild, emerge the gentoolkit in the portage |
| 44 |
tree to get it, and check out the documentation to see what else it |
| 45 |
includes! |
