The patch doesn't prevent the issue from occuring. It merely delays what seems the inevitable, a hrtimer clock min delta of HUGE ns on the guest.
Yesterday i did some stress-testing with a patched guest kernel. It seems a high CPU load on the kvm host machine triggers the issue.
The guest ran in SMP mode (2 cpu's). Currently i've got it running with one cpu for over 12 hours. No hrtimer messages in my dmesg as of yet.
What the * is going on here?
Does lucid have this problem as well?
