I'm getting Frequently freezes on Ubuntu, usually when I'm browsing the web.
For now I can say that I was using almost all the RAM memory and was high on I/O activity just before the system hung.
At first I thought the problem maybe was Chromium's, since almost all the time I was using it. Recently I was trying Firefox (so I could "test" this hipothesis) and BANG! Same thing happened.
Maybe the problem isn't related to OS, but the fact that I can't to do anything but a hard reset makes me feel (besides angry) the OS should offer a last resort to the user, so one could at least try to kill a suspect process. In my case, all the time it happens, I try to open system monitor or a terminal window without success: the PC doesn't seem to "listen". Some times even the CAPSLOCK light can't change state when I press that key.
The only thing I could do (a couple of times) was getting to terminal through ctrl+alt+fn, but it took a long time after the keypress and, once there, each character took several seconds to print on the screen. One of the times I even ended getting a "login time out" warning, since the system didn't finish fast enough the login process.
I'll try to get more precise and useful information as soon as I know how to do it, so I can help more.
