kernel hang at boot time

[hazif81]

i upgrade my kernel from 2.4.32 to 2.6.15, but when i reboot the kernel, it hang until ..
root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.15 root=/de
[Linux-bzImage, setup=0x1400, size=0xd5272]


what's wrong with that...

Well, my first guess would be that your "root=" parameter is out of wack! Assuming your root partition is on hda1, since you're calling saying root is hd0,0, it should say something like root=/dev/hda1.

[hazif81]

is it bcause of that? mm.. i tried to boot using old kernel, the root also like that..can work..
never mind, i try to do it...thnks..

what does your

/mount/boot/menu.lst or grub.conf contain.


I would try reinstalling grub to:
as root

grub
root (hd0,0)
setup (hd0)
quit

WARNING: This will overwrite you mbr so don't do this if you have other distros or OS's installed without careful thought.

just so everybody knows

the root (hd0,0) in grub actually refers to where /boot resides? If this is also where / resides then fine but it doesn't mean root in the literal since it means boot.

for example i have /boot on hda2 / on hda6
so my grub is

root (hd0,1)
kernel /boot/kundera root=/dev/hda6 ro

but if I didn't have a seperate partition for /boot then it would be

root (hd0,5)
kernel /boot/kundera root=/dev/hda6

this in my grub.conf

I don't understand why there is so many entries but it looks like your problem is in grub.conf/ menu.lst your root is listed as:

root (hd0,1) when if you use root (hd0,0) at the grub prompt it works. So just change the entries to the 0 0 format.

one question though. Does your windows entry work?

And maybe i'm confused from your original post but my impression was that grub hangs untill you tell it the location of root (hd0,0) and then it boots up for you. If this is wrong then please explain further the error you are getting and also list things like

/etc/fstab

opss.. sorry, i post wrong grub.conf file..this is the one. actually i did cross compile, all put all libraries inside another machine..timeout 5

root (hd0,0)
kernel /vmlinuz-2.4.31 root=/dev/hda4 panic=10 acpi=off ro console=tty0 console=ttyS0,57600

my old kernel was 2.4.31, then i upgraded into 2.6.15, it hang like i said before..it stop until..

root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.15 root=/de
[Linux-bzImage, setup=0x1400, size=0xd5272]

[spencerf]

so this is your current entry

title IPCop(2.4.31)
root (hd0,0)
kernel /vmlinuz-2.4.31 root=/dev/hda4 panic=10 acpi=off ro console=tty0 console=ttyS0,57600

and it works when you use vmlinux-2.6.15 ??????

if so then just change your entry to the 2.6.15 kernel instead tof the 2.4.31 kernel.

[hazif81]

kernel 2.4.31 is my old kernel. i put inside the grub.conf file, so next time when i reboot, i can choose desired kernel.. but for a meantime, i boot with kernel 2.6.15 (by default it reads from System.map-System.map-2.6.51 in /boot/), which is this one in grub.conf..

title IPCop
root (hd0,0)
kernel /vmlinuz root=/dev/hda4 panic=10 acpi=off ro console=tty0 console=ttyS0,57600n8

i'm sorry. i dont know how to explain it in a proper english...
