Comment 21: >> If still reproducible, please post results following: >> https://wiki.ubuntu.com/DebuggingKernelBoot This is not applicable as booting is successful >> https://wiki.ubuntu.com/DebuggingSystemCrash I reproduced the crash and tried "Alt+SysRq+1" followed by "Alt+SysRq+t". As the display was frozen with the blue-white pattern I did not see a traceback.

Obiously, the kernel is in a very bad state. Do you see a good chance that a crash kernel would get activated in the situation above? > Did you checksum the ISO you downloaded?

When I mount the burned ISO file, the "properties" menu and "du -s" tell me the correct size (thus, the "dd" copy may do something wrong). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1649566 Title: [GeForce 7025 / nForce 630a] System freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1649566/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
