I installed Gentoo on a pc104 embedded system using the experimental/x86/embedded/stages/stage3-x86-uclibc-2006.1.tar.bz2 stage file. I needed to kill some process and when I executed ps I got "segmentation fault". /proc is mounted so I tried each binary of sys-process/procps-3.2.6 and they all end in a "segmentation fault". I though that I did some error while installing the embedded system, so I try to install (with vmware) a gentoo with uClibc. I downloaded the stage file and made chroot /mnt/gentoo .... when I execute ps I get a "segmentation fault".

After some time with Google I found a thread in the uClibc mailing list with the same problem. http://www.busybox.net/lists/uclibc/2004-August/009731.html But I wasn't able to fix the problem in my vmware test installation.
