The bug on is BUG_ON(!(*sptep & PT_PRESENT_MASK)); In kvm_zap_rmapp While moved around a bit [1] the check is still present today.
It seems it bails out when trying to zapp a shadow page table entry that is still present. I can't see from the trace how this might have happened. Further evaluation up to the kernel experts, but maybe the pointers help them to identify a known fix.
