Public bug reported:

[Impact]
This impacts 2 socket Cavium ThunderX systems using pass-1.1 silicon, and can result in IO hangs.

[Test Case]
$ dmesg | grep "ITS command queue timeout"

[Regression Risk]
The workaround is in gicv3 specific code, and only activated when the hw revision in the IIDR matches ThunderX pass 1.x silicon, so risk to other platforms is minimal.
