Nice writeup. Thank you for this investigation.

Yes, please try.

Maybe we are missing some instruction barriers when
reading the tsc counter?

The issue is hard to reproduce for me, i have no issues
with qemu or real hardware. I guess it also depends on
the host cpu and linux scheduling and the moon phase :(

Anyway, dont give up. It would be very nice to get to
the bottom of this.
