"Segmentation Fault" error.

**Pete** · 04-05-2006, 10:15 PM

When I try to boot Knoppix on my other PC (1.3GHz, 128MB RAM, CD-ROM drive) it works fine. Yet when I try to boot it on this PC (2.9GHz, 512MB RAM, DVD+/-RW drive), I get a "Segmentation Fault: Please Check" error during the boot process. I've tried all of the cheat codes outlined here, and none of them have worked. Any suggestions or ideas would be greatly appreciated.

Also, I would like to point out that I have also used my Knoppix CD on my schools computers and it has worked fine. I don't know the specifications for those computers, but I do know that they have CD-ROM drives. Is it possible that my DVD drive is the cause of the error? If so, how do I fix it?[/url]

What speed did you burn the cd at?

**Pete** · 04-06-2006, 10:13 AM

4x

Well. it's not burn speed then but it does sound like someting that could be caused by a bad burn, marginal media, a scratch on the disc or even, yes, the DVD drive. If you have not done so already I would try booting a different piece of media. If that fails in the same way and you can swap drives then that might help. And if you have both a DVD and a CD drive in that system try booting from the CD drive. Smart Boot Manager will let you boot from a second optical drive even when the BIOS insists on booting only from the first optical drive.

I'm getting a segmentation fault too:

I recently downloaded and burned a Knoppix V4.0.2-CD to be able to have a simple Linux workstation to play with and connect to my Linux server without trashing the kids' (other OS) stuff. It works great at home on my AMD Athlon 2600+ (1.8 Ghz?) unit with 512Mb RAM & 80G HD. However, the same CD just locks up on my work PC: HP Pavilion Pentium(R) 4 at 3 Ghz with 1.49 Gig Ram, 30Gig NTFS HD (but that shouldn't matter, should it?) and dual graphics: Intel 82915G/GV/910GL and NVIDIA GeForce4 MX 440.

I've tried various boot options like:
knoppix 2
knoppix vga=0
koppix acpi=off pnpbios=off noapic noapm
knoppix vga=0 debug -b 3
failsafe debug -b 3
All lock up after Autconfiguring devices is "Done."

The most informative boot I was able to obtain was via "knoppix expert debug":
Autoconfiguring devices... _______ Done.
Mouse is Generic PS/2 Wheel Mouse at /dev/psaux
/etc/rcS.d/S00knoppix-autoconfig: line 846: /bin/loadkeys: Input/output error
Segmentation fault
Your mouse has been autodetected as: /etc/rcS.d/S00knoppix-autoconfig: line 903: /usr/bin/awk: Permission denied

then I can type away on blank lines, but nothing ever happens until I turn the PC off.

Any ideas?

I know that this isn't really much help, but my friend also has an Hp pavilion PC, a slightly older version one (mabe 1.3-1.4ghz?) and the only live-cd knoppix that it will run is Accelerated knoppix,I have no real idea why that is. If I had to guess perhaps HP hardware (much like many lazer printers) has some strange quirk that is optimized for windows (not that hardware companies ever sleep w/ M$) that doesn't understand the way the kernel in linux does read/write operations

At any rate if you do try acceleated knoppix be sure to do the

Code:

knoppix lang=us

boot option, otherwise it will boot in Japanese.....

I'll burn the CD this weekend and let you know Monday! Thanks for the tip.

Accelerated KNOPPIX didn't boot on the HP either, but DSL booted up. It had some disk read errors (I didn't catch whether they were CD or HD, they went by so fast, but it booted up to GUI without any stops).
Hmm....
The Accelerated KNOPPIX stopped after HWSETUP "Setting up ALSA [ok]." I'll have to try my home unit again to see what it was trying to do after that.
