Production silicon will not have this\nissue, so there is no plan to push this upstream. However, it would be valuable\nfor users evaluating this silicon if Ubuntu could carry a workaround for this\nissue for the 17.10 cycle. Given that this workaround is coded to only activate\non this specific silicon (and only compiled-in on arm64), regression risk\nshould be negligible.\n\nJayachandran C (2):\n UBUNTU: SAUCE: ahci: thunderx2: Fix for errata that affects stop\n engine\n UBUNTU: SAUCE: ahci: thunderx2: stop engine fix update\n\n drivers/ata/libahci.c | 17 +++++++++++++++++\n 1 file changed, 17 insertions(+)" }
