Hello, Few days ago I installed FC11 (after few months with FC9). Soon after the installation, while watching various updates being downloaded and installed, I opened the system monitor and saw 4 separate CPU graphs, one per core, just like I did under FC9 before. Few days later, after downloading "gkrellm" I noticed that I can't set it up to show 4 separate CPU graphs as I had under FC9, only one common CPU graph. Checking the system monitor I saw that now it too shows only one CPU graph (despite correctly detecting "AMD Phenom(tm) 9550 Quad-Core Processor". Playing with the "top" command "1" to switch between "Cpu(s)" statistics and per-core statistics I see that in the "per core" mode only Cpu0 statistics is shown. It looks like my system suddenly became non-SMP. I don't remember altering the kernel (yet. I need to add a SCSI driver so I'll need to recompile the kernel but I haven't read enough explanations of where to get the sources and how to recompile the whole kernel), I remember downloading gkrellm-2.3.2-2.fc11.src.rpm after precompiled binaries from gkrellm-2.3.2-2.fc11.x86_64.rpm didn't show the 4 separate CPU graphs, and I also downloaded "nedit" both as binaries and as sources and attempted to compile, got and error: nedit: error while loading shared libraries: libXp.so.6: cannot open shared object file: No such file or directory added to the LD_LIBRARY_PATH the directory: /usr/lib64 which changed the error to: nedit: error while loading shared libraries: libXp.so.6: wrong ELF class: ELFCLASS64 I also changed the shell used from bash to tcsh (in /etc/passwd, I hope it's correct), but I don't see how this may affect the non-SMP issue. Although I have 12 years of UNIX/LINUX experience at work, it had always been as a user, so I'm a novice LINUX "sysop" and probably made some stupid error somewhere. Can anyone give me some direction as to where to find the source of the sudden change of my system behavior? The output of "uname -r" is: 22.214.171.124-191.fc11.x86_64 Thank in advance for any help, Arie.
