I am attempting a fresh install of Ubuntu. I've gone through the install process several times. I experience crashes after booting into the new system, or sometimes before finishing installation.
The crash: Video freezes completely, without warning. Mouse cursor will move. Ctrl+Alt+Bksp does nothing. I cannot Ctrl+Alt+F2 into tty2. I can Alt+SysRq+REISUB and reboot the computer. Crashes seem semi-random, but they will occasionally appear while installing Ubuntu, while using Gparted, or while switching themes.
The troubleshooting: This computer runs Windows 8 with absolutely no problems, including 3D gaming. I ran memtest86 through 5 passes with no errors. I tried installing Ubuntu 16.04 and 14.04. I tried limiting max_cstate to 1 in GRUB_CMDLINE_LINUX
. I tried installing to a different hard drive, with all other hard drives physically unplugged. I tried installing all available software updates immediately after booting into the new system. I tried updating the Linux kernel to 4.8.12, even beyond what is available in an Ubuntu release. The crash occurs regardless of whether I am using the nVidia video driver or open-source driver.
The only thing I see in /var/log/syslog
is repeated resetting of some USB devices, sometimes rapidly. http://paste.ubuntu.com/23596804/
My hardware: Motherboard AsRock 970DE3/U3S3, CPU AMD 4 GHz FX-8350 8-core, RAM 2x4GB G.Skill F3-14900CL9D-8GBSR at 1600MHz, GPU EVGA GeForce GTX 550Ti
I am absolutely at my wit's end here. What else can I check?
/var/log/syslog
or/var/log/syslog.1
around the time of the crash/hang? It should give you a clue if you can find out what was going on just before.
