Hello! I've a problem with my configuration and maybe someone of you can help me out. My system looks like this: Abit NI8 SLI mother board CPU Pentium-D 2,8 GHz (dual-core) 1 GB DDR2-RAM (one module) 2x GeForc7800GTX grahpics adapter (to connect three monitors) kernel 2.6.17-rc1 (vanilla) My problem ist, that a "cat /proc/cpuinfo" show's just one cpu-core if I boot with ACPI enabled. If I disable ACPI by removing it from kernel or by passing 'append="acpi=off"' to my lilo.conf, the system is going unstable. It is freezing sporadical without any trace output. The freezes occur after a short time, especialy when I run OpenGL-applications - but also without OpenGL! I have collected some information about my system here: -------------------------------------------------------------- dmesg's output with acpi-debug enabled in kernel: http://www.kpage.de/dmesg_acpi3.txt My kernels ".config"-file: http://www.kpage.de/config.txt The output of "cat /proc/interrupts" when ACPI is enabled: http://www.kpage.de/interrupts_acpi3.txt The output of "cat /proc/interrupts" when ACPI is disabled: http://www.kpage.de/interrupts_noacpi3.txt The output of "cat /proc/cpuinfo" if ACPI is enabled: http://www.kpage.de/cpuinfo_acpi3.txt The output of "cat /proc/cpuinfo" if ACPI is disabled: http://www.kpage.de/cpuinfo_noacpi3.txt And last, but not least: the output of "acpidump": http://www.kpage.de/acpidump.txt -------------------------------------------------------------- I've started a discussion about this problem on the linux-smp mailinglist. You can find some more information about what I've done by now here: http://marc.theaimsgroup.com/?l=linux-smp&m=114421848813280&w=2 I have also contacted nvidia and abit - without response from abit by the time... Who can give me a little help? Thank you very much!!!
