View Full Version : how to diagnose kernel panic

January 7th, 2013, 06:41 AM

I encountered on several occasions kernel panic by pluging in and unpluging my usb logitech webcam on my christmas setup.

New system:
i5 3470
asrock h77 pro4/mvp
ssd samsung 830
8gb g.skill

At first I was trying to install SL6.3. But I had some problems, so I decided to install xubuntu12.04. Installed my stuff(virtualbox, vmwareplayer, audacious, qmmp projectm, audacity, nautilus) and just when it started to feel cozy enough to migrate my data the problems came back: qmmp froze, virtualbox froze, desktop wallpaper disappeared till reboot and then I had my first kernel panic in years. The behaviour is not constant; sth it just freezes the system, sth nothing happens.

What I tried:

updated uefi-bios, no effect
booting 12.10 12.04 live ubuntu and xubuntu, nothing happend but reacted a bit slow
memtest doesn't start, not live and not from grubmenu, my display powers off and I can hear the fans running; I even tried to replace mt86plus with mt500b1.bin (http://forum.canardpc.com/threads/68001-Memtest86-5.00-Beta-available-!-Need-betatesters-!), didn't work

Any suggestions how to further proceed?


I returned mainboard and ram to my reseller. In case this doesn't solve my problems I create a new thread.
