That is 16045693110842147038 ( or 0xdeadc0dedeadc0de ) + some offset. It appears the kernel is accessing from / writing to un-allocated pages, and results in corrupted memory. > Whole system freezes requiring reset, partial freeze, network reset, cons= ole corruption, panic. To be clear, is that the host but not the VM freezes ? Does older 15.0-STABLE or 16.0-CURRENT work good ? --=20 You are receiving this mail because: You are the assignee for the bug.=
