Benjamin, this is an older kernel and the issue might already be fixed, but I thought you would want to see this.
Thanks Josh for notifying me. The call stack suggests that the pagefault is triggered when writing events to the node (in the same way evemu does). This is not a nominal use case, so I'd like some more information on how the bug was triggered. JPRochette, please provide the user-space program that triggered the bug (if any and if you are able to reproduce it). Also, I'd like to know which event node triggered the page fault.
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously.
