i'm running your timer-test script with an earlier config you sent
(kernel-2.6.13-i686-smp.ccrma.config), on a similar SMP box, and i'm not
getting these timeout problems (using -rt9). How easily do the above
problems reproduce - does it happen right after bootup?

(to make sure could you send me your current SMP .config too? You have
CONFIG_KTIME_SCALAR disabled, right?)
