Hello All, I kindly ask for your support. On my MythTV frontend-only machine, I had to replace the motherboard. The old motherboard was an ASUS P5KR (Intel P35 chipset), and the newly installed motherboard is an MSI P43T-C51 (Intel P43 chipset). The old MB wasn't faulty - I just had to urgently use it in another machine. Everything else in this system remained basically the same - CPU, RAM, Video, etc. My video adapter is NVidia 8600GT made by ASUS (don't remember the model exactly). I am using proprietary NVidia driver from rpmfusion. With the new MSI MB, the system just stops responding when trying to boot into graphical mode (runlevel 5), and there seem to be no errors in /var/log/messages, dmesg or in Xorg.log. If booted in runlevel 3 (text mode), the system seem to work, but there are several kernel oopses coming right after boot: 2010-03-01T22:19:06.175302+03:00 frontend1 abrt: Kerneloops: Reported 1 kernel oopses to Abrt 2010-03-01T22:19:06.175409+03:00 frontend1 abrtd: Directory 'kerneloops-1267471146-1' creation detected 2010-03-01T22:19:10.113246+03:00 frontend1 abrtd: Getting local universal unique identification 2010-03-01T22:19:10.119410+03:00 frontend1 abrtd: New crash /var/cache/abrt/kerneloops-1267471146-1, processing 2010-03-01T22:19:10.138685+03:00 frontend1 abrtd: Registered Action plugin 'RunApp' 2010-03-01T22:19:10.138735+03:00 frontend1 abrtd: RunApp('/var/cache/abrt/kerneloops-1267471146-1','test x"`cat component`" = x"xorg-x11-server-Xorg" && cp /var/log/Xorg.0.log .') 2010-03-01T22:21:06.111275+03:00 frontend1 abrt: Kerneloops: Reported 1 kernel oopses to Abrt 2010-03-01T22:21:06.111358+03:00 frontend1 abrtd: Directory 'kerneloops-1267471266-1' creation detected 2010-03-01T22:21:06.175171+03:00 frontend1 abrtd: Getting local universal unique identification 2010-03-01T22:21:06.179860+03:00 frontend1 abrtd: New crash /var/cache/abrt/kerneloops-1267471266-1, processing 2010-03-01T22:21:06.179881+03:00 frontend1 abrtd: RunApp('/var/cache/abrt/kerneloops-1267471266-1','test x"`cat component`" = x"xorg-x11-server-Xorg" && cp /var/log/Xorg.0.log .') 2010-03-01T22:23:06.112950+03:00 frontend1 abrt: Kerneloops: Reported 1 kernel oopses to Abrt 2010-03-01T22:23:06.113047+03:00 frontend1 abrtd: Directory 'kerneloops-1267471386-1' creation detected 2010-03-01T22:23:06.176437+03:00 frontend1 abrtd: Getting local universal unique identification 2010-03-01T22:23:06.181005+03:00 frontend1 abrtd: New crash /var/cache/abrt/kerneloops-1267471386-1, processing 2010-03-01T22:23:06.181066+03:00 frontend1 abrtd: RunApp('/var/cache/abrt/kerneloops-1267471386-1','test x"`cat component`" = x"xorg-x11-server-Xorg" && cp /var/log/Xorg.0.log .') If I do an 'init 5' while I'm in runlevel 3, I can see Xorg starting and occupying all of the CPU resources (so that my PC doesn't respond to keyboard at all, and remote SSH sessions are also interrupted). Again, I don't see any obvious error messages in the logs when the system stops responding... I made a 'yum update', getting all the packages up to date. It didn't change the behavior at all... I thought I could reinstall the system completely, but Fedora 12 install DVD also stops responding shortly after the "Check installation media" step - before actually starting the installation. At the same time, Fedora 12 Live CD boots up fine (in Gnome) but stops responding after a few minutes. I thought this could be a hardware issue. I checked the RAM with memtest (well, 2 passes went without errors, then I interrupted it). Then I installed Windows XP - to test if it will fail. XP worked good, I installed all the drivers and noticed no stability problems at all. So this looks more like a software incompatibility to me, rather than a hardware issue (still, I'm not 100% sure)... Unfortunately my knowledge of Linux isn't any good to be able to track the problem. Could you please help me to investigate it further? I can run any tests / provide logs, dumps, etc. Just need to know where to go and how to look for a solution... Thanks!
