Unfortunately memory corruption is hard to track down because the messenger is usually not the one to blame. Perhaps enable slab debugging and see if it turns something up. Could be also broken hardware. Does an older kernel run stable? If yes and if it can be reproduced bisecting would be good. -Andi - 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/
