Verified on trusty and utopic, both by myself and several users. But I haven't been able to reproduce it on an earlier linux-generic-lts- vivid release. Not sure if a different gcc version is used to compile vivid, preventing the bug from showing itself. (Considering the original commit) I'll

I never looked into vivid before. So I didn't know whether the problem also occurred on vivid. I've run the testcase for several hours now on the older 3.19.0-16, without crash. But on vivid there's a lot more commits on vdso:

I had a couple of users test 3.13.0-54 and 3.16.0-39 proposed. After more than 24h they haven't experienced a crash whereas before it would likely crash between minutes to an hour. Please note we also now confirmed earlier suspicions that the issue didn't only happen on VMs but also physical

I tested the patches earlier, so it should be good. But just for the record: I just pulled the trusty master-next branch, built and tested on the test vm. The crash doesn't occur for me anymore in the reported scenario. Atm, it looks like the fix will be in 3.13.0-54 but afaik we have to wait for

Interesting that I didn't find this bugreport earlier. Samuel, can you look at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1450584 to see if that's the problem OpenSim experiences? If so, try compile the master- next branch of trusty to see if it fixes the issue for OpenSim. Originally
