To fill in a few details. This was triggered in the middle of a kernbench run on the machine. A job with just dbench runs in it ran to completion. The machine is a 4 node numa x86_64 system. Seems that most schedular options are on: CONFIG_FAIR_GROUP_SCHED=y CONFIG_FAIR_USER_SCHED=y At the moment we don't have any historical jobs back from 2.6.23 so I cannot be more specific as to when it arrived in mainline. The x86/x86_64 merge broke our build process; a bad assumption here, not a problem with the merge. -apw - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
