[gentoo-amd64] urgent: Segfaults after synchronously emerging|downloading 30GB|burnng a DVD iso image

[Dieter Ries]

Hi,

i have a very severe and urgent problem:

We had a gaming party tonight, and this morning at about 6 AM i was downloading 30GB of data from the local network, emerging world and burning a DVD iso image with K3b. 

Then the emerge stopped with some error i dont remember, and after that, everything got somehow slow. because i didnt want the dvd to be ruined i waited till it was burned and the 30G were downloade. during my waiting i tried $top or $ps -A to see the running processes, but i got "Speicherzugriffsfehler", which is AFAIK the same as segmentation fault.

i got it for everything i tried, and when i tried something from the KDE menu, nothing happened.

then i tried another console using Ctrl-Alt-F1, but when i typed the username, the cursor went down about ten lines and that was all, i could not write anything anymore.

when the data was downloaded and the dvd burned, i tried to shutdown from KDE, no success. the i tried to shutdown from the console, no success either. in the end i had to use the reset button.

then, just after "freeing unused kernel memory" there are many errors, all looking quite the same, something like:

[hotplug]<some hexcode, each different> Segmentation Fault
<something cryptical> Error 4

init hung at that state, nothing worked.

so i got my livecd, botted from it, then i ran fsck for all the partitions, without any errors or anything, everything seemed fine.

i then mounted my system and home partition and proc and typed 
chroot /mnt/gentoo /bin/bash, which was followed by, guess it:
segmentation fault.

the data on all my partitions from sda5 to 10 is still there and i can mount them all, but i cant chroot and i cant boot.

so no gentoo anymore, and to get a working system i tried to install debian etch quickly, which didnt work because of no NF4 chipset support n the dvd.

so in the end, i am now using knoppix 4.0 to write for help.

is there any chance to get my gentoo back to life without completely install it again? and why does the system break when doing some things simultaneously?

can this be a hardware issue? i am using an athlon64 3000+ on an elitegroup NF4 board with NVidia GF 6200 TC PCIx Grafics-Adapter, 2x512MB of RAM, Single channel, and my Maxtor 7V300 with 16M of buffer.

I hope someone can help me soon, because I need my computer to work with.

cu and Thanks in advance,

Dieter
