With "cached read" HDD testing and multiple ports busy on a SATA host controller, 3726/3826 PMP will very rarely drop a deferred R_OK that was intended for the host. Symptom will be all 5 drives under test will timeout, get reset, and recover. Submitted by: Rich Futyma <rich.futyma@sanmina.com> MFC after: 2 weeks
