After trying changing all elevator options, and many suggestions out there, I've checked irqbalance. In /etc/default/irqbalance, I've changed in my Ubuntu 12.04 LTS 64-bit notebook, ENABLED from 0 to 1, as follows:
root@XXX4:/etc/default# cat irqbalance #Configuration for the irqbalance daemon #Should irqbalance be enabled? ENABLED="1" #Balance the IRQs only once? ONESHOT="0" All freezes stopped (of course when swapping occurs is definitely slower than RAM). Only occasional sloppiness in the mouse/keyboards remained at sustained swap operation moments. My notebook is an Lenovo IdeaPad G530, with a CPU Intel Dual Core T3400 2.16GHz with 4 GB RAM. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/159356 Title: System freeze on high memory usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/159356/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
