Yep. Here are what I get in my dmesg. The lines below are output when the kernel is started (just after the bootloader): Mar 3 16:50:35 joule kernel: assertion failed /usr/local/src/kvm-15/kernel/mmu.c:722: (gpa & HPA_ERR_MASK) == 0 Mar 3 16:50:35 joule kernel: audit error: (pre page fault) levels 2 gva 444000 gpa ffffffffffffffff hpa ffffffffffffffff ent 3e369021 Mar 3 16:50:36 joule kernel: assertion failed /usr/local/src/kvm-15/kernel/mmu.c:722: (gpa & HPA_ERR_MASK) == 0 Mar 3 16:50:36 joule kernel: audit error: (post page fault (fixed)) levels 2 gva 444000 gpa ffffffffffffffff hpa ffffffffffffffff ent 3e369021 Then the kernel takes a huge time to boot, and at then end of the kernel boot, or maybe when trying to start init, the following lines are printed hundred thousand of time: Mar 3 18:40:30 joule kernel: audit error: (pre page fault) levels 2 gva ffffffffbfbfe000 gpa 1e81e000 hpa 4749c000 ent 564ca825 Mar 3 18:40:30 joule kernel: audit error: (post page fault (fixed)) levels 2 gva ffffffffbfbfe000 gpa 1e81e000 hpa 4749c000 ent 564ca825 -- .''`.
