That's very odd indeed, non of my test systems nor Ingo's ever triggered this, and that patch has been in -tip for a rather long time. CommitDate: Tue Sep 30 12:35:20 2008 +0200 That's 3.5 months of test time.. most curious. What kind of userland do you have that triggers this? -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
