Segmentation Fault when "Bringing lo up"

Hello everyone,

<WARNING>big post</WARNING>

The following has happened in two completely different servers.
It has happened with both gentoo-dev-sources(2.6.8-r3) and development-sources(2.6.8.1).

First PC config :

Coppermine celeron 850 (tested and works fine with fedora C2, mandrake 10 and 2004.1 Gentoo networkless install)
128mbram
2* 18GB U2W LVD SCSI drives
cflags: -o3 -pipe -fomit-frame-pointer -march=pentium3
USE=-alsa -qt -gtk -gnome -kde -dvd -cdr mysql

The problem has happened when doing either a stage1 or stage 2 or stage3 install.

Second PC Config

Sempron 3100+ (tested and works fine with fedora C2, mandrake 10 and 2004.2 stage3 with 2.4.26-r9)
512MB RAM
2* 40GB ATA100 drives
cflags -o3 -pipe -fomit-frame-pointer -march=athlon-xp
USE=-alsa -qt -gtk -gnome -kde -dvd -cdr mysql
the problem has happened with stage3 and stage2 install.(stage 1 not performed but i think it wouldn't work either)

All the installation process goes on without a hintch, not a single error.
I have done it more than 7 times combined on these two pcs verifing each and every step of the way.
The result is the same

I think a good strategy to find the failure would be to test this with one of the various Linux LiveCDs like knoppix.

The gentoo LiveCD booted without problems? (should due to the install attempts)

Does the kernel compile without any warnings or errors?

The gentoo Live-CDs (both 2004.1 and 2004.2) booted with no problems whatsoever, detecting all hardware (except via-velocity).
Kernel compilation went on with no errors and no warnings for both gentoo-dev-sources and development sources.
The gentoo-sources kernel compiled exactly in the same environment (same pc, same Live-CD) and installed as label gentoo with lilo boots up with no problem. Development sources (or gentoo dev sources, no matter) installed with lilo as label gentoo-dev in the same environment, hangs after throwing the seg fault i mentioned before ...

I even emerged apache2, mysql, gpm, pine and so on with the gentoo-sources (2.4.26-r9) kernel getting no errors and all work just fine.

I think that this is some kind of kernel bug ... booting through another distro wouldn't mean anything since gcc and all the tools are created into the chrooted environment and thus not affected by the install environment, but i will try that just in case :wink:

If that doesn't work and no one comes up with something, i will post a bug report.

Thank you for the idea

Oh, sorry, I missed the point.
I thought not only the dev kernels but even all kernels fail with this seg. fault! :oops:

Unfortunately I don't know how to debug a kernel yet. So can't help further!
Maybe it's time for you to report a bug.

For those interested, all the problems with the via-velocity driver seem solved for me with gentoo-dev-sources-2.6.9-r1
