@Mathieu: You were right, there was a program eating the CPU. This wasn't shown in the attachments above because I took ~3 minutes to turn on the other computer and log the output requested after the freeze.
But today it crashed and the other computer was already on, so I could check `top` immediately and it showed that kontact was using "101%" of the CPU. It surprised me because everything was working fine, it must have reached that point in one millisecond. I logged that and came to launchpad.net to attach such file, but as usual my computer froze (this time without kontact open) and I went to the other computer to log `top` with the new freeze, but by mistake I overrode the previous file -- and this time, top showed no program using more than 10% of the CPU. -- [Jaunty] My system freezes several times a day; Ctrl+Alt+Backspace doesn't work. https://bugs.launchpad.net/bugs/375358 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
