I have Ubuntu 11.10 (Oneiric Ocelot) on my PC. PC has Intel DH61CR motherboard. Whenever I try to reboot or shutdown my PC, it will freeze, vieweing only Ubuntu logo with white dots under it on violet background. I always have to use physical reset or shut down button to do what I want. Help me out please!

do you have squid or any proxy server installed? –  shantanu Oct 17 '11 at 9:46
    
Nope, not as I know. –  Marko Oct 17 '11 at 10:25
    
After reboot see the log file for error that occurs during reboot or shutdown. see /var/log/kern.log or /var/log/dmesg –  shantanu Oct 17 '11 at 10:48
    
I added logs, i see no errors. –  Marko Oct 17 '11 at 12:03
