Hello everybody!
I'm GULDO, new here!
I just found out this site I was anaware of!
I was looking for help with a kernel problem.
I compiled and installed 2.4.18 and 2.4.20 before, with no
problem at all, but now I can't get 2.4.22 to work.
I tried 7 different configs for it, with no luck.
The thing is that I get this error:
VFS: cannot open root device "210b" or 21:0b
Please append a correct "root=" boot option
Kernel panic: VFS: unable to mount root fs on 21:0b

I know there are some posts here about this, but I
still need help. I tried some options fot boot, such as
mem=192M or root=/dev/hde11, but this is not working
at all.
I tried even to copy my config for 2.4.20, which works,
but I still had no luck.
So what's wrong with me?!?
Would you please help me?

Thanks a lot,

Guldo

What does your lilo.conf file look like? Seems as if it can't boot cause its not finding your root partition, etc, or something along those lines.

Here's my lilo.conf; everything works but the default...

lba32
disk=/dev/hde
bios=0x80
boot=/dev/hde
root=/dev/hde11
install=/boot/boot-menu.b
map=/boot/map
delay=20
prompt
timeout=100
# prompt
# single-key
# delay=100
# timeout=100
vga=normal
default=Linux

image=/boot/vmlinuz-2.4.22.310803.2
label=Linux
read-only
append="hdb=ide-scsi"

image=/boot/vmlinuz-2.4.18.270803
label=Linux_18
read-only
append="hdb=ide-scsi"
# restricted
# alias=1

image=/boot/vmlinuz-2.4.18-bf2.4
label=Linux_bf2.4
read-only
# restricted
# alias=2

image=/vmlinuz.old
label=LinuxOLD
read-only
optional
# restricted
# alias=3

image=/mnt/tmp/vmlinuz-2.4.20-686-1.250803
label=DebianBunk
root=/dev/hde6
read-only
append="hda=ide-scsi hdb=ide-scsi"

other=/dev/hde2
label="Winzozz"

Try adding root=/dev/hde11 in the config of the default instead at the top of your configuration. I personally will have a root= for each image, not just one global one at the top of the lilo.conf file.

i think he just forgot to include VFS soupport in his kenrel.... donno why it'd be needed, and dont know why he'd recompile 7 times and still not put it in.... but?

Putting one more root=/dev/hde11 in lilo.conf was useless.
D'oh! I didn't realize that about VFS! So it is a file system?!?
WOW
Ehm.... which one, among the following?!?

Thanks a lot,

Which one is the right item for VFS in the kernel config?

Thanks,
