I don't think there was an email thread on the RCU stall issue after all. I'm not sure what how it was fixed. The 60 second time out would have still triggered with my bug. It was a complete system hang, the RCU stall message was just a debugging hint. I was hitting the bug every couple days reliably on all my systems. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
