I am wondering if it is due to slub code. I begin to wonder if this might be the result of a compiler bug. The kernel in question was compiled with gcc version 4.7.0 20111117. And there was commit to the gcc repository today that looks suspicious: http://gcc.gnu.org/viewcvs?view=revision&revision=181466 Will have to dig deeper, but if this turns out to be the cause of the issue, I apologize for the noise. -- Markus -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
