every linux i try to boot whether its a live cd or a complete dvd

dvd installs and then fails to boot

latest i tried mandriva spring edition 2009

i have a portable usb drive in which i install my linux everytime its a seagate free agent go

i always used it for my linux which i frequently change

i am not able to boot into any linux since i installed a graphics card xfx geforce gts 250 in my system

there is a kernel panic whenever i try to boot something

sometimes its like
"
cannot execute "/sbin/mingetty"
"


"
/etc/rc.d/rc.sysinit: line 473 : 1171 segmentation fault modprobe scsi_hostadapter> /dev/null2>&1
"

either of them for any given flavor


Pls help me i have tried too many installations

Well, first things first;
Are you able to successfully boot a "Live" CD or DVD of a Linux distribution?
if so, find out if you have a "lshw" command, then run it and post anything that looks like it's related to the USB drive (that would basically be anything USB or SCSI related)

Also, find out if you have an "lsusb" command, and give that a run, too.

P.S: List the name and version of whichever Linux Live CD you use. (Suggestion: knoppix)

it maybe worth running in interactive mode if the live disk supports it and work slowly by turning off detection for usb based devices.
Few basic things to check as well is that you have enough power to run this system okay since it maybe possible that the detection pushes your psu harder. am not certain but i know boots are stressful to a system.

i have used suse ubanti live cds recently both didnt boot my computer

and i have installed mandriva and debian lenny which didnt boot after they got installed from the cd

i am using vista and xp which boot perfectly so i dont think its a power problem

I thought it was worth mentioning on the offchance that it may have been relevant.
I'll be honest and say i dont know what the problem is but i've got some things for you to try which may narrow down what the problem is.
It says there is a problem with scsi. You dont use any scsi based adaptors do you?
try and edit the boot options for the live disks something like boot parameters etc
try these in turn and remove the "quite" and "splash" options so we can see where it goes wrong before the kernel panic

noscsi (disable scsi detection)
nousb (disable usb detection)
failsafe (disable almost everything in order to get the system to boot)

failsafe is probably the best to try first

actually if i install the linux in a usb drive
so if nousb is used it will not find the root only........
anyways i'll check the rest of the options but i have checked failsafe and it didnt work......

none of the options work when apic is off i get the sbin error and when it is on i get the bigger error

Have you tried replacing your HD with a new, unformatted, one and installing to that? (I presume you want to keep your Window$ systems intact, and yanking the drive would do that.) What I've done for at least one of my desktops (an HP that came with Vista installed) was you yank the SATA Vista drive, purchase a SATA USB drive, swap the drives, and boot Vista from the external drive on those rare occasions when I want to use it. The SATA drive from the USB drive works fine in the HP box with Fedora 11 and Ubuntu Jaunty on it. Note that the USB SATA drive enclosure has, in addition to the USB port, a direct SATA cable port that I use rather then trying to boot Vista through a USB port, since, if I were to do so, Vista might then "think" I was trying to pirate the precious MS IP.)

Anyhow, my basic point is that you don't really need to be able to boot from a USB drive.

----------------------------

That being said, have you checked that your BIOS supports booting from a USB drive, and that your USB drive using the version 2 USB hardware that is needed for a boot to work? (On my systems, I can't boot from my "legacy" USB drives, only the version 2 ones.) This is not likely to be your problem, since you report that the boot has started and then failed, whilst the "version" problem prevents the boot from even starting. But this comment might help others reading this thread.

Do you have any unusual settings like ahci enabled on your sata devices? i had loads of problems with that where it wasnt supported until kernel 2.6.27

i used to use linux a lot and it never was a problem .......... until i installed xfx gts250 after which i was not able to boot any live cd or boot after installation ... so i think settings should not be a problem

hmm this sounds a bit beyond anything i could help with really i'd recommend filing a bug report in ubuntu or something and see if they can help you better. Might also be worth going to ask nvidia for support since it's their product that caused the problem

Here's a thought: From your description (problem after installing XFX) it might be that the XFX is requesting a large memory segment from your BIOS, and the BIOS is not doing it properly so your video memory is being "shared" with the memory that the Linux initial RAM disk "thinks" is free. So the USB DVD buffer and the video buffer are trying to use the same block of memory, which would,of course, really make it hard for the DVD to be read correctly. (Memory allocation and usage in Windows is done differently for the way it's done in Linux systems, so the allocation problem - if that's what it is - may not be so apparent with your Windows systems.)

Anyhow, check to see if your hardware vendor has an BIOS update available that you could install. If so, install it.

You could also see if changing the memory available for the XFX card (e.g., aperture size, etc.) in your BIOS makes any difference.

this kinda looks like the problem............... lots of memory errors in the boot also

no bios update available last bios update for my system was in 2007 the modal is 946giz http://downloadcenter.intel.com/filt...s=44&submit=Go!

and no option to change the memory available to graphics card

any other solution u have for this kind of problem...... please

have you tried any of these live linux distributions?

slax
http://www.slax.org/

grml
http://grml.org/

both can be installed and run from a cdrom or a usb stick

the problem doesnt seem to be with usb drive as they are not needed for live cd

the memory conflict seems to be the problem
