I want to lodge a low priority bug with the Linux / PowerEdge Engineering team, but I can't find how to do that on any of Dell's Linux pages, so I'm posting here.
We're running a 3.18 kernel on a CentOS 6 base OS and OMSA 7.4 installed. I'm periodically getting this error message on our hardware running this kernel:
kernel: Allocating domain for dcdbas failed
That error messages comes from intel-iommu.c (http://lxr.free-electrons.com/source/drivers/iommu/intel-iommu.c?v=3.18#L2944).
I've tracked down to what triggers it, it's the OMSA init scripts that call either smbios-sys-info or smbios-sys-info-lite, which are doing stuff inside /sys/devices/platform/dcdbas/, I'm not sure what specifically.
Does anyone know who'd be interested in this bug/error?
