But I refuse to believe it can be a hardware problem, because 10.2 had

Maybe it is not indicating a hardware failure, but the source of the
problem.  It sounds like it is related to your clock problem.  Perhaps
tsc is often marked as unreliable for a reason.  Maybe try jiffies,
since the acpi_pm seemed to cause your clock even more problems.

I just tried, and my system crashed:

echo jiffies > /sys/devices/system/clocksource/clocksource0/current_clocksource


I tried again, in runlevel 3, and I discovered that the clock stopped. I tried again to go back to tsc, but the clock continued stopped. I tried to reboot, and reboot crashed.

Is no good.

 * acpi_pm looses time, like several minutes per hour.

 * tsc "appears" to work well, but might be suspicious

 * jiffies doesn't even work, time stops, applications depending on the clock
   stop - even "halt" stops when issuing a beep because the beep never times
   out.

 * pit I haven't tried. Should I?
