Bug description:
[Impact]
Booting a Cavium ThunderX node in ACPI mode results in constant messages like
this to the console:
arm-smmu arm-smmu.1.auto: Unhandled context fault: fsr=0x80000402,
iova=0x0fffc000, fsynr=0x10081, cb=1
In some configurations, this causes the SATA controller to fail to
initialize, making the system unbootable.
[Test Case]
Boot a Cavium ThunderX node w/ the kernel parameter "acpi=on" and watch the
console.
[Regression Risk]
