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, 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 hangs when booting 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!
