paravirt clock stil causing hangs in kvm-65

[Nikola Ciprich <extmaillist@linuxbox.cz>]

Hi,

I also tried paravirt clock again in latest git with kvm-65 patch 
applied, and problem with cpu-lockups persists:

Can I somehow help to track this one down??

Additionaly, I'd like to ask two questions:
1) why is kvm-65 patch changing release to -rc7? maybe this is 
unintended??

2) I'm getting lot's of following messages on host, what do they mean?
[16836.605669] Ignoring de-assert INIT to vcpu SOMENUMBER
[16836.605687] SIPI to vcpu SOMENUMBER vector 0xSOMENUMBER
