 Posted: Wed Jun 15, 2005 4:46 pm Post subject: Problem booting new gentoo installation [solved] |
 |
|
I installed gentoo on my htpc. When I booted it, it got an error very soon after booting. In /etc/lilo.conf I set the root partition for booting gentoo to /dev/sda5, and made sure my kernel had the nvidia sata driver. I really don't know why it can't mount my root partition.
Error:
| Code: | VFS:Cannot open root device "805" or unkown-block(8,5)
Please append a correct "root=" boot option
Kernel panic not syncing: VFS: unable to mount root fs on uknown fs(8,5) |
Specs:
Gentoo 2005.0 Athlon XP Stage 2
lilo
AMD Athlon 64 3700+
Asus K8N-E nForce 4 Ultra
1GB PC3200 RAM
/dev/sda: 120GB SATA hard drive, / is /dev/sda5
/dev/sdb: 300GB SATA hard drive
/dev/hda: CD-RW drive
Edit: It looks like I forgot to inlcude /dev/pts in the kernel. SOLVED

The kernel panic states it's an unknown file system. Did you compile support for your root's file system IN the kernel (not as a module)? |

oh and your grub.conf as well... its saying your "root=" part isn't right for some reason...

# Should work for most systems, and do not have the sector limit:

# If lba32 do not work, use linear:

# MBR to install LILO to:
boot = /dev/sda
map = /boot/.map
# If you are having problems booting from a hardware raid-array
# or have a unusual setup, try this:

#disk=/dev/sda bios=0x81 # see this as the second BIOS disk
#disk=/dev/hda bios=0x82 # see this as the third BIOS disk
# Here you can select the secondary loader to install. A few
# examples is:
#
# boot-text.b
# boot-menu.b
# boot-bmp.b
#
install = /boot/boot-menu.b # Note that for lilo-22.5.5 or later you
# do not need boot-{text,menu,bmp}.b in

# Adding the following line to /etc/fstab should take care of this:

Perhaps you should pass udev to the kernel as the handbook suggests?

It only suggests it for genkernel users, which I didn't use. |

Even so, the 2005.0 build has caused udev related boot problems, which some users have overcome by adding udev or nodevfs gentoo=udev.
