Code:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,3)


Serdecznie witam :)
Swiezo po instalacji gentoo x86 (obok windy) wg. oficjalnego tutoriala otrzymalem wspomniany komunikat. Rozumiem przez to, ze niewlasciwie skonfigurowalem kernela. Probowalem roznych kombinacji (wg. google) jednak nic nie przynosi skutku.
Z gory dziekuje za pomoc :)

Bardziej pomogłaby informacja :
- jaki typ partycji założyłeś na /
- co masz w GRUBie
- jaki masz układ partycji (fdisk -l)

Od razu sprawdziłbym czy przypadkiem nie sformatowałeś partycji na ext4, a domyślnie nie jest ona wybrana (jest w File System).

w grubie podajesz sda3 zamiast sda6. z sda3 grub czyta obraz kernela, initramfs o ile jest i tak dalej. root= jest przekazane do kernela i to musi byc rootfs.
