It would be interesting to know what memory model is being used in each case. Both CONFIG_HIGHMEM* and maybe user/kernel split might play.
Based on one boot with one machine, 4G RAM, it didn't hang. Unfortunately a production machine, I was playing following some "unscheduled maintenence." -- bill davidsen <davidsen@tmr.com> CTO, TMR Associates, Inc Doing interesting things with little computers since 1979. - 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/
