|
|
error is common one...sorry. munt VFS file system error, blinking cursur on the top left. After I use genkernel all, then if I go to /usr/src/linux and do make menuconfig to add things like support for KVM, my machine become unbootable. Why is this? What am I doiing wrong? Making one change in kernel .config file should not make machine un-bootable...
just wondering ... |

you could try genkernel next.
anyway why do not you try to build your own kernel? |

can you post a link to your /usr/src/linux/.config in a pastebin?
what does "eselect kernel list" say?
what is the output of "fdisk -l"
is the initrd setup correctly in grub? |

I thught it was Gentoo things to do and thought everyoone compiles ownn kernel...whens some option is missing from kernel I have to go in and manually make changes and make make && modules_install

There's your problem - Funtoo overwrote your Gentoo installation with its own grub config. |

Moved from Kernel & Hardware to Unsupported Software.
Funtoo isn't Gentoo and we don't want gentoo users being mislead. _________________ Regards,
