Samsung's page for the drive also says it supports NCQ= : I seem to have the same problem, just not as frequent: four drives of t= his type, connected to an SiI 3132 and an nVidia MCP55; resets occur on bot= h controllers, and only with this drive type, not with several Maxtor 6B2= 00M0. I never thought to check, but all drives on the nv controller have NCQ disabled according to /sys/block. So maybe it's not (directly) NCQ rela= ted?
