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".

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 Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1649566 Title: [GeForce 7025 / nForce 630a] System freeze Status in xorg package in Ubuntu: Incomplete Bug description: Yesterday, I upgraded from Ubuntu 12.04 via 14.04 to 16.04. From 14.04 on, I was unable to graphically log in. A few seconds after the login (varying between 1 and 10 s), the screen changed to a pattern with dense white stripes on the violet/red background, and X froze (no reaction to mouse or keyboard). The latest messages in "/var/log/syslog" each time showed varying "nouveau E" problems, e.g. "unrecognized interupt", "PFIFO", or "PBUS" problems such as e.g.: "nouveau E[ PBUS][0000:00:0d.0] MMIO write of 0x01f70001 FAULT at 0x00b010" (values and addresses varying). Usually, the freeze happens when e.g. "firefox" is started (which happens in my context automatically after a graphical login). In my case, the NVidia driver could not be started (I did not investigate why). Using boot parameter "nouveau.config=NvMSI=0" made the graphical login successful again. Today, I wanted to report the bug with "ubuntu-bug". However, during the collection of the system information, the error happened again (despite the "nouveau.config" boot parameter).
