Arthur,
I list all the information I have right off the bat:
AMD Opteron Model 246, 1 MB L2 Cache 64-bit processor Model : AMD Opteron Model 246 Core : Hammer Operating Frequency : 2 GHz Cache : L1/128K, L2/1024K Socekt: Socket 940
Is that info enough?
I just remembered looking at /var/log/dmesg again. There was a line that said that IOMMU was not enabled in my BIOS, and that I should enable it. However, I can't see any option in my BIOS for enabling/disabling IOMMU.
Thanks, Saurabh.
