hi

i've recently installed centos 5.3 on the machine.
the installation went fine, but after that (on the first boot) it says
a lot of segmentation fault errors

fe.
# yum
Segmentation fault

i've tried centos 5.2 and 5.0 also, but none of them works.
but the centos 4.x works fine.

could anyone tell me where the problem is?
thanx a lot
