Comment 380 for bug 124406

I'm sorry for flooding this thread, but I have more experience to share.

After another reboot in "clocksource=jiffies" mode, I saw that 1 OS second passes in real 0.5 seconds. But the rest of the system was pretty stable. Keyboard auto-repeat was twice as fast, but did not get triggered inadvertently.

I did another reboot in "clocksource=jiffies" mode and opened the online clock application. Initially the clock speed seemed normal. After 20-30 seconds it became twice as fast.
Then from the console, I started an application with an infinite loop therein. That made the clock seconds turn very very fast. Probably CPU speed has influence here.

Good news is that when I changed the boot option to "clocksource=tsc", I got stable results even after a few reboots. Seconds seem to pass as fast as they should be.
