Critical bug: VT-d fault causes disk corruption or Dom0 kernel panic.
All,
We met several system failures on different hardware platforms, which are all caused by VT-d fault.
err 1: disk is corrupted by VT-d fault on SATA.
err 2: Dom0 kernel panics at booting, which is caused VT-d fault on UHCI.
err 3, Dom0 complains disk errors while creating HVM guests.
The culprit would be changeset 19054 "x86_64: Remove statically-partitioned Xen heap.".
