For more than a month now, I've been running a Dual Xeon 2000 system (IBM eServer xSeries 225) with 5.3-RC2 and later upgraded to 5.3-RELEASE and I have no problems at all. Hyperthreading is disabled in BIOS, ACPI is enabled.
Excuse me for jumping into this thread but could you elaborate as to why you have Nyperthreading disabled?
I'm afraid I can't give you any good technical reasons. I simply think of HTT as Intel marketing blurb, meant to make you feel like you are getting two CPUs for the price of one. Well, actually it's still only one CPU. I've been running another single Xeon 2.4 box for more than a year. Initially, I ran several months with HTT enabled. Then I ran several months with HTT disabled. I didn't really notice any performance difference.
Well thanks for sharing those observations. Until I read what you said I *assumed* that there was a performance difference with HTT enabled. The specs seem to show that there *is* a theoretical difference, yet clearly according to your observations there just isn't any difference of earth shaking proportions.
Much appreciated!
Regards,
