 Posted: Mon Dec 20, 2004 12:23 pm Post subject: Solved: Hang after "Ok booting the kernel" |
 |
|
Hi,
is someone of you familiar with this problem: I recompilied my 2.4.25 kernel, unfortunately copied it over my old working one (yes yes, i learned from this.. :s ) and rebooted. Now the system just displays grub and after that "OK booting the kernel.." and thats it. No more output.
But the weird thing: Booting sounds normal. Hdd does all familar "sounds" and i think the system boots fine. I can even press ctrl-alt-del to reboot. logging in doesn't work..
maybe someone has an idea whats going on.
now i can only boot from live-cd and chroot in my system. in a few hours i can paste the kernelconfig. i have checked the config but it seems ok. in a few hours i can paste the config here..
btw: when i chroot from livecd in my system i do following steps:
| Code: | mount /dev/hdd5 /mnt/gentoo (hdd5 is my / )
chroot /mnt/gentoo
source /etc/profile
env-update |
did i forget something important while chrooting?
any hint is appreciated

Hi,
hmm, sounds interesting 
two rather quick-and-dirty things you can do:
1) if you have enabled frame buffer console, disable it, maybe that's what is causing the lack of further output.
2) in your chroot-ed environment: enable the sshd | Code: | | rc-uptdate add sshd boot |
and log in from a remote station... maybe you can derive that way some "irregularities".
but in any case: I'm looking forward for your detailed config.
cheers, R.

No frame buffer console here

Sshd is already running but I can't ssh or even ping that machine. So unfortunately I can't dmesg, too. But maybe there are some logs. Have to check that later.

I think your chrooting is wrong... you should follow this sequence;
| Code: | chroot /mnt/gentoo
env-update
source /etc/profile |
because the env-update generates info in /etc/profile.env ... your sequence loads incorrect data into the ram... off course this doesnt solve your problem but it's pretty important to chroot right into your new environment...
Can you give us the 'kernel' line in your grub.conf? Except if you are sure the line is okay... |

| AFAIK env-update only regenerates /etc/profile from /etc/env.d so if you changed nothing in there you should be fine without it. |

hi,
so here is my .config and messages (too large to put in here).
grub.conf
| Code: | title=Gentoo Linux 2.4.25
root=(hd1,5)
kernel (hd1,5)/boot/2.4.25/bzImage root=/dev/hdd5
|
kernel
| Code: | livecd / # ls -l /boot/2.4.25/bzImage
-rw-r--r-- 1 root root 1069854 Dec 20 02:10 /boot/2.4.25/bzImage
|
mountings
| Code: | livecd / # mount
/dev/hdd5 on / type ext3 (rw,noatime)
none on /dev type devfs (rw)
none on /proc type proc (rw)
/dev/hdd6 on /boot type ext3 (rw,noatime) |
machine's configuration:
celeron 433
192 ram
kyro2 gfx
realtek 8139 lan
hardware itself is working as it boots from livecd.
anything else important i forgot to post?

yes you forgot 
wrong:
| Code: |
chroot /mnt/gentoo
env-update
sorce /etc/profile
|
true:
| Code: |
chroot /mnt/gentoo /bin/bash
env-update
source /etc/profile
|
recompile your kernel, and use 2.6.x maybe better

does it make a difference? (i don't know)
so if i recompile the kernel after chrooting this way there is a chance it works? |

in the file "messages" (link is 3 posts above) there are some errors when it tries to insmod 8139cp but i think this is not the reason for the main problem.
hm, but maybe thats why network doesn't work. i recompile kernel and put network drivers inside.
do you see any problems with console-related stuff in my config? i can't remember that i changed anything in this section.. |

hm i thought about switching to 2.6.x too but i don't think this resolves my problem. if it works again and i have some free time, i switch
but another thing about my console settings: do you have "VGA text console" enabled? i think it doesn't deal with "frame-buffer support for console" as it is in another section. hm, i just switch it on and test |

i think the reason was "VGA console". so listen everyone: never turn it off at least in 2.4.x
cheers and thanks for all answers

cool - I'm glad it works now.
to answer the question about chroot: if you don't specify the interpreter then the default will be used (at least on that machine here - it's not a gentoo box, so I'm not sure if it's that way on all distributions)
cheers, R.

thanks, i'm so happy too took me 2 weeks to figure it out. now i will save any working config and just diff the last operation one with a modified if it doesn't work
| Quote: |
then the default
Code:
/bin/sh
will be used (at least on that machine here - it's not a gentoo box, so I'm not sure if it's that way on all distributions)
|
bash already default on my box and that's why i didn't notice any difference. thanks anyway for info.
