Booting with clocksource=tsc still hangs in what appears to be the exact same place.
Screenshots for that are available here: http://rtr.ca/hrtimers/
Of possible interest is that the bottom of the 25line screen capture differs somewhat from the 50line capture.. see for yourself. This is 100% consistent from boot to boot.
Using CONFIG_DETECT_SOFTLOCKUP=y eliminates the problem, so that's really got to be a huge clue, somehow ?
Meanwhile, I'm going to try a libata patch I just saw posted by Tejun. - 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/
