An update from today's testing: We went through the test case today, and began testing older kernel releases to see if we could find a bisection point. These tests were run on three different SandyBridge machines, with 1gb, 2gb, and 3gb of memory. All using a dual core chip.
In any case where there was a failure, we hung < 5 iterations through the reproducer. In any case where there was success we went beyond 20 (even 35) iterations. Using the Kernel Team's mainline builds from here: - http://kernel.ubuntu.com/~kernel-ppa/mainline/ Working: v2.6.37-natty & v2.6.37.6-natty Failing: v2.6.38-rc1-natty We've even seen the same failure up to 2.6.39-rc3 There is ~8000 patches between 2.6.37 and 2.6.38-rc1, requiring 13 bisections from what I gather. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/755066 Title: heavy i/o on sandybridge systems with small memory footprints causes system hangs -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
