Re: 2.6.18.2: sporadic SATA port resets (Broadcom BCM5785 (HT1000))

Hello, Emmeran. There is no logged error on drive's side. Only timeouts on host's side with BMDMA engine running. I dunno specifics of the severwork controller but many controllers with BMDMA interface timeouts the command if transmission failure occurs, so my primary suspect is still hardw
