 |
|
Hello all gentoo´ser.
i got a problem at two ways.
After i recompiled the kernel with i get an | Code: | | can´t mount /dev/hda3 at /newroot |
. So i started again with the livecd and typed | Code: | | find / -type f -exec grep newroot {} \; -print > file |
to find all the stuff that contained that string. The system gaves me the linuxrc file in /usr/share/genkernel/generic/, but after one time i find that it was never found. I dont saved this file and i dont find it.
So i recompiled the kernel with make. But after that i get an kernelpanic | Code: | can´t find something at block(3,3)
its nice if you can help me and if not.
regards gentux |

| You should try to configure and compile the kernel manually. |

Make the kernel by hand as instructed in the manual:
1. cd /usr/src/linux
2. make menuconfig
3. configure your kernel. Make SURE you get everything you need. If you aren't sure, press H for help. also, emerge pciutils because lspci is your friend.
4. make
5. emerge module-rebuild && module-rebuild rebuild
6. make modules_install install
7. edit /boot/grub/grub.conf. It should look similar to this:
| example grub.conf, with vesafb-tng, asuming /boot is hda1 and / is hda3: |
default 0
hiddenmenu
timeout 5
splashimage=(hd0,0)/grub/splash.xpm.gz
title=Gentoo Linux
root (hd0,0)
kernel /vmlinuz root=/dev/hda3 vesafb:mtrr:3,ywrap,1280x1024-32@85
|
8. reboot and enjoy your kernel |

thx,
after years of reading i got the information that devicedrivers for PCI is not good as module.
what do i with emerge module-rebuild && module-rebuild rebuild. is it faster as the way to recompile all again.
yes my grub.conf is the same until vesafb...
wath is with genkernel an the information that mount will mount /dev/hda3 at /newroot?
many many thx and maximus successus |

| module-rebuild is a tool that automatically re-emerges packages that install kernel modules. It's pretty awesome. |
