>APM seems to be preventing use of the TSC timecounter. Otherwise >the clock would go non-backwards 233/17 faster :-). The whole problem may be caused by APM. APM's time handling is of low quality. Among other bugs, it assumes that inittodr() has a resolution of about 1 usec. inittodr() actually has a resolution of about 1 second, so the time may be set wrong by up to +- 1 second after even a short suspension. This may cause the time to go backwards if the suspension period is shorter than 1 second.
