Gentoo hangs at boot time ... [Solved]

Mehrius · n00b Joined: 14 Jul 2005 Posts: 23

So the kernel is 2.6.11-gentoo-r3 but I also got 2.6.12-gentoo-r4 and no change

The whole boot process stop for about 20 secs at a line that says :

ide1 at 0x177-0x177,0x376 on irq15

and then boots up as if nothing happened .... I used other linux distros and didn't get this so it's not a real hardware error...

please post anything that u think might be usefull.....

Mehrius,

Do you use ide1 at all?
Thats /dev/hdc and /dev/hdd. If not trun it off.
The driver is waiting for a timeout if there is nothing there.

I have no idea what that ide1 is for ....

Can you tell me how I can find out what uses it or how to disable it ????

Thanks for the reply...

Mehrius,

The kernel checks for a number of Iintegrated Drive Electronics (IDE) interfaces to see if they hve hard drives or CD-ROMS (or DVDs) attached as it starts. They are known as ide0 (the first one) ide1 and so on.

Thank you for the reply .... I thought it will solve it but :

I run ide1=noprobe .... it just hangs at ide0 now stays on it for 20 secs and goes on ...

If I run ide0=noprobe I get a kernel panic (quite normal as my hda isn't loaded anymore)

If i run hdb=noprobe and hdd=noprobe it still hangs at ide1 .............

So maybe it's not something from the ide ??? but what is it then????????

Mehrius,

The 2.6.12 kernel has a option to put timestamps on messages.
Its enabled in make menuconfig under Kernel hacking at Show timing information on printks.

Turn that on, rebuild your kernel, then post your dmesg.

this is my timestamped dmesg:

I think this is the relevant part and you can clearly see that it takes a LONG time for the system to probe ide4 but when I boot I just see ide1 at 0x170-0x177

I'll try boting with ide4=noprobe .......

Hey guys, what can I add at the end of the grub line to prevent a service from running? Apache2 has hung there and will not get passed that I can get into the server. Even if I select "single" mode, the system still runs the services to get to that prompt. Pls help, teh box has been down for some 12 hours now!!!! :cry:

JulesF,

Boot with the liveCD,
mount your partitions
chroot

rc-update apache2 del

Thanks NS. I couldnt find my boot cd previously but a mate has just burned me a fresh copy so I have changed rc-update. Is it /etc/innitab I have to change to havr the system boot up with the CLS login? At the moment, when it boots back up it changes to the GUI login and because I do not have "X" installed it hangs on the GUI login screen..

Cheers. The system now hangs on xinetd. I have had to take out, spamd, local and usermin to get this far. Do I take it that the server is now broken? All this because someone else was installing VHCS, via SSH, in my absence! :cry:

This looks more and more like a reinstallation job. I cannot get into the box to check where the logs are at. I can't even mail the guy in the States who caused all this as the mail server is down.

Luckily I have MX rercords for each of my domains after the last failiure.

JulesF,

Hmm. xinitd is another service started by rc-update. You know how to fix that.
I could say 3rd time lucky :) but run rc-update -s and see what else looks new.
Shift and pageup together allow you to scroll back on the console.

Hey NS, it would appear that it does not matter what I take out of rc-update, the system will simply hang at the one previously. It hangs at Webmin now which I installed about two weeks ago even thought this has got [ok] next to it.

I think this may be the time nearing "disaster recovery." I dont suppose there is a way that I could rebuild Gentoo without having to scrap the previous install? This is going to cost me big as it is a production server.

A lot of these errors on screen:

JulesF,

That respawning too fast is a well known problem.
I think it relates to ptys and the lack of them.
Have you been compiling your kernel recently ?
Or has someone else been doing it for you?

Check the compile time stamp in
