Package:toshutils Version:2.0.1-12 When I start the computer with slow cpu speed (set from within /etc/init.d) on my Portege 7020CT laptop, time begins to run much too fast (roughly 3 seconds to every real second). If I then run "toshset -cpu fast", I get the following error message in my kernel log, and time returns to normal:
Aug 7 15:12:00 portege kernel: Losing some ticks... checking if CPU frequency changed. Aug 7 15:12:00 portege last message repeated 75 times Aug 7 15:12:00 portege kernel: Losing too many ticks! Aug 7 15:12:00 portege kernel: TSC cannot be used as a timesource. Aug 7 15:12:00 portege kernel: Possible reasons for this are: Aug 7 15:12:00 portege kernel: You're running with Speedstep, Aug 7 15:12:00 portege kernel: You don't have DMA enabled for your hard disk (see hdparm), Aug 7 15:12:00 portege kernel: Incorrect TSC synchronization on an SMP system (see dmesg). Aug 7 15:12:00 portege kernel: Falling back to a sane timesource now. The problem does not seem to occur if I start the computer and then, after init has run, call "toshset -cpu slow" manually.
