Ensure your BIOS supports the stepping of the Opterons you have. Eg, if
you have the Iwill H8501, BIOS v1.8 [1] covers all the current
steppings. You may even encounter problems if you mix different
steppings.

I find the ondemand governor works as expected with 2.6.12 on my
Athlon64 Winchester [1]; as soon as I bzip2 a file, processor freq is
pinned at 1.8GHz and drops to 1GHz when idle.

Hello,
I've two Iwill 8way Opteron equipped with 8 Opteron 875 CPUs each.
(In the past we build some systems with singlecore CPUs and they went
very well)
The Problem now is that the machines crash during boot when maxcpus is
greater than 8.
2.6.12-rc4 works well with maxcpus=8, with 9 or more it
3 matches
