Please make sure your BIOS
OK ... at first glance the system seems to be operating "normally" except
for the errors every 4 seconds ... that is it's attached to and using the
iscsi target ...
Is this a problem in iommu OR the emulex driver??

Hello All wonder if there has been any movement on this issue I'm
having a similar issue
I'm running an HP dl380 gen 8 with an Emulex OneConnect 10Gb iSCSI (14e4:164c)
(rev 11)
also known as " Hewlett-Packard Company NC373i Integrated Multifunction Gigabit
Server Adapter"

Hi Yijing,
These devices don't support Phantom Function (PhantFunc 0).
Could you please help to provide full dmesg, /proc/iomem, and ACPI
DMAR table? You may get DMAR table by:
acpidump > acpi.bin
acpixtract -a acpib.bin
iasl -d DMAR.dat
Thanks!

Hi Yijing,
Could you please help to provide detail information about the
PCI device, such as "lscpi -vvv"? It seems like that "Phantom
Functions" is enabled with these PCI devices.
Thanks!

We found some strange devices in HP C7000 and Huawei Server. These devices
can not be enumerated by OS, but they still did DMA read/write without OS
management. Because iommu will not create the DMA mapping for these devices,
the DMA read/write will be blocked by iommu hardware.
