2019-03-05 19:31:51 dann frazier description [Impact] During heavy load, the following message may appear on the console of a HiSilicon D06 system: arm-smmu-v3 arm-smmu-v3.3.auto: CMD_SYNC timeout This is due to a bug that can also impact system performance, as the CPU is blocked until the timeout occurs. [Test Case] The Ubuntu server certification test suite hits this pretty reliably during the stress-ng tests, although I haven't narrowed it down to exactly which test yet. [Regression Risk] Limited to arm64 systems. This change has been upstream since 4.20 w/o any noticed regressions (based on lack of Fixes: commits). Regressions could manifest as a performance hit.
