We'v been test driving one box with openSUSE 11.0 on an i7 920 since around 1 June. The only issue I've seen is in the /proc/cpuinfo display :
processor : 7 vendor_id : GenuineIntel cpu family : 6 model : 26 model name : Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz stepping : 5 cpu MHz : 1600.000 cache size : 8192 KB physical id : 0
I can't quite figure out why the cpu MHZ is quoted as 1600 when it's otherwise a 2.67GHz cpu. I think it is power-saving feature. When there are no heavy apps running CPU is working at 1.6 GHz, but when u launch some heavy apps, it goes full speed at 2.66 GHz.
That sounds like a reasonable explanation
I have just done a few tests, and that IS indeed the explanation.
Does "top" show the correct number of multiple CPU's and HyperThreads? As I understand it, the Nahalems bring back Intel's old hyperthreading to give the appearance of multiple CPU's on one die. The one I'll probably try has one chip containing four discrete cpus, each cpu with two threads, giving the appearance of eight cpus.
