Let me > try Linus tree... Thanks for your help with testing this patch-set, but I recommend to wait for the next version, as review already found a couple of bugs that might crash your system. For example there are NMI cases that might crash your machine because the NMI happens in kernel mode before the cr3 switch. VM86 mode is also definitly broken. I am about to fix that and will send a new version, if all goes well, at some point next week.
