Hi David I have not tried yet to repro #49361 on 3.6.6, but, as you say, if there are no core VM changes, I am confident I can do so just by doing # echo always > /sys/kernel/mm/transparent_hugepage/enabled I am at your disposal to test further, and, if there are patches, to try them out. Note that I only once experienced a crash for which I could not find relevant info in logs. But the hanging processes issue could always be reproduced consistently. have a nice day -- Marc Duponcheel Velodroomstraat 74 - 2600 Berchem - Belgium +32 (0)478 68.10.91 - marc@...line.be -- 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/
