Yes my machine also has an i7 930 in it. I have not yet checked the interrupts during the time when the system is experiencing high cpu system usage, but I will do so when i see it happen next (I know when it's going to happen because the cpu widget i have jumps up from 5% to 100%) I did install htop and I noticed that my cores crazy when it occurs, before I was using KDEs system monitor and had noticed the same thing.
One thing I have noted is it seems to happen more when I am running a VM, (but it does happen when I'm not as well). Also I'm using sysfs.conf method to tell /dev/sda to use the noop scheduler instead of CFQ as I heard that was better for SSDs. I'm using CFQ for my other disks however. -- Timer interrupt freezes, system becomes sluggish https://bugs.launchpad.net/bugs/665796 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
