4 months ago I bought a new and expensive computer. I was using Ubuntu with Gnome for 5 years (now I was with Gnome 3).
Yesterday my LibreOffice crashed, then I had to kill Java, then the graphical environment freezes, then reboot without graphical acceleration, report bug to nvidea... every week I have a really hard crash in some application.
I am running a linux desktop on Linux 10.04 and started a new server system on Linux 12.04. Both systems have samba installed. I tried to mount the desktop system on the server. The mount worked ok but when I accessed the mounted folder, the desktop system crashed completely (no mouse or keyboard activity) thus the only way to get the system back was cutting the power.
Ubuntu 12.04.1 with all updates installed. Laptop Lenovo Thinkpad X230 with Intel Corporation Centrino Advanced-N 6205.
WiFi sometimes becomes extremely slow. Often this occurs when I wake the system from suspend and connect to a different network. I find no obvious clues in system logs. /etc/init.d/network-manager restart doesn't help, but a reboot does.
Thanks to the Intel TCO watchdog some servers i manage now reboot on a kernel or hardware crash and init scripts are now even 'rebootsafe'.
I have a first generation Starling (star1) that I've just updated to 12.04. (All software is up-to-date; the System 76 drivers have been reinstalled.) The 'restart' command that is offered at shutdown causes the computer to begin its shutdown procedure, but then it just stops: the screen goes black but the power remains on. It does not reboot. Pressing the power button shuts down the computer.
We recently set up a new Ubuntu 12.04LTS server on our network. It's not fully configured so it's not doing much beyond sshd and a default apache2 install. But this evening it appears to have crashed. It wasn't responding to the network or the keyboard.
I'm implementing a Reboot() call in my application. It's an embedded application, so no console, keyboard or power switch. The Reboot() must eventually restart the system no matter what. Ideally, I want it to fail gracefully.
I've had systems in the past cause problems where a call to reboot or shutdown did not result in a reboot of the machine. e.g.
Outline:
I use the way shown on http://ubuntuforums.org/showthread.php?t=35087 to backup my linux system, but somehow when I restore it, it crashes.
Problem Description:
When I reboot, there's an information:
Gave up waiting for root device.
I installed VMWare player just to play with it.
Everything was good until my PC crashed going into suspend mode.
When I rebooted, my network was disabled.
when I typed
ip addr
There were no eth0 adapters there, but there were a vmnet1 and a vmnet8
Much later I solved this problem by going to Network connections in the Ubuntu System menu, adding a wired connection, and then enabling the network
