There were several responses to my initial note that the time of day clock in FreeBSD 4.3-RELEASE runs faster than real time (gaining up to an hour every day, where the amount of clock speedup is in proportion to the load on the CPUs) on my SMP boxes. In these responses, others mentioned they see similar behavior on other hardware. I see this behavior on Intel STL2 and Tyan S2567 motherboards with dual 1 GHz P-IIIs installed. To wit, the archives: http://docs.freebsd.org/mail/archive/2001/freebsd-smp/20010617.freebsd-smp.html Is there any SMP developer I should directly notify (though I presume he already reads -smp), in the interest of having this fixed for all SMP users? Or is it low priority, compared with other SMP development work underway? Or is there reason to believe that -CURRENT would behave better?
