I'm using a supermicro computer with 4 dual core AMD opterons.
In the past, I had been running CentOS 5.1 with no problems whatsoever. However, I recently began using a new piece of software which gave segmentation faults when I attempted to run it. The vendor states that RHEL 5 is not supported for this software and suggested I downgradge to RHEL 4.
So, I obtained a copy of the CentOS 4.6 DVD and installed it. The install went fine. However, when the system boots, if I let it go to the smp kernel, it crashes after about 2 minutes.
If I choose the UP kernel from the GRUB boot menu, it runs fine (I'm actually posting from that now).
Does anyone know of any issues with CentOS 4.6 and multi processor machines?
FYI - I'm currently doing kernel updates and hoping that will fix my problem. I'll report back after my reboot
