I tried the approach from comment #30 and also comment #37 with ami- fa01f193 in us-east. This runs a 2.6.32-312.24 kernel currently in proposed and was running on hw that showed 6M cache in cpuinfo. Both methods did not cause the scheduler bug for me.
I will have a look at the source code and see whether something can be found there. This unfortunately is a bit bulky. -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/708920 Title: Strange 'fork/clone' blocking behavior under high cpu usage on EC2 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
