When either/both of CONFIG_NO_HZ, CONFIG_HIGH_RES_TIMERS is used,
the 2.6.21 kernel hangs on startup just after printing one/both of these:

That's a hard hang, by the way. No magic sysrq key or anything.

Well, in case this helps. If I take the exact same .config that fails,
and add *only* this to it, it then boots just fine.

CONFIG_DETECT_SOFTLOCKUP=y
