hmmm, that's very hard for us to analyze. We did meet a similar oops before because of the heavy workload and CFQ block IO scheduler. Could you a test for us? change your default Block IO scheduler from CFQ to deadline and run LXC as usual to verify this issue is gone. I'm just guess and hope this can do some help.
