I just got a PE 2950 and I'm having some problems. I installed 6.2PRE and it went well. The first thing I noticed is that immediate as BSD start to load, a bold/highlighted message says "768xxx bytes above 4G ignore" or something like that (don't recall what xxx was. Next thing I noticed whilest trying a buildworld against the latest stable sources. My system detects 8 cpus. It actually only has 4 - 2 dual core xeons. I'm guessing that the others are from hyperthreading, but I'm not certain. Hyperthreading is disabled by default, I believe. So, in the process of make buildworld -j 32, I noticed that only even numbered CPUs are being used (0,2,4,6). Is that because BSD is ignoring the HT CPUs, which would be 1,3,5,7? top and iostat both show that I was never able to exceed 50% overall CPU usage. Is that because even though I have the HT representations disabled, the OS is using their availabilty in calculating % idle time? Is there any way to get an accurate number? The PE doesn't let me disable HT, I don't believe. Finally, after the upgrade, I'm having a problem with the system hanging on startup right after the firewall message, and sometimes right after the CD ROM detection message. I believe that the SAS controller is supposed to be detected next, and I'm assuming that's the problem. When I first tried to install, I used 6.1, and it completely didn't recognize my SAS controller. I found a message in the archives that suggested trying the latest stable source, so I tried 6.2 and it worked. Any ideas what could be causing the problem? When I was using the 6.2PRE ISO, I had to restart a few times before it got past that stage also. Thanks much!
