I experience this bug all the time from at least 2 years. The issue started for me when I switch to 64bits ubuntu version. I'm a web developer and chrome is the main cause of this issue. Ubuntu starts to swap and all freezes until the application that is causing this stops or turn idle. CTRL+ALT+Fx and force kill works, but it is a sloooow proccess because the system turn very very very slow and the ctrl+alt+fx change + login + write the kill command takes a frustating long time that most of times I prefer to reboot hardly the PC.
I've experienced this issue in many laptops (HP, Asus, dell) and in a desktop dell machine. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1555351 Title: High load freezes ubuntu completely everytime (have to reboot) Status in linux package in Ubuntu: Incomplete Bug description: Whenever an intensive application runs which consumes lots of memory or hard drive i/o, Ubuntu freezes completely. It is even impossible to kill the offending task. Only "solution" is then to wait for the application to finish, or restart PC. Windows doesn't have this issue as bad as Ubuntu, in that Windows is always somewhat responsive, and you can attempt to kill the intensive application to recover the system.
