After months of trying to figure it out and insane "Hardware_ECC_Recovered" error values, I found that the error was with the power connector plug / sata HDD interface. All errors disappeared after replacing that cable. Since you have error on more than 1 HDD, I suggest: 1. Check smartctl output for each AND all HDD 2. Check whether your power supply unit is still healthy or if it is supplying inconsistent power. 3. Check the main power supply line and whether it shows any voltage fluctuations or if there is a new heavy consumer of amps on the same power line as the server is plugged to. -- View this message in context: http://freebsd.1045724.n5.nabble.com/AHCI-timeout-when-using-ZFS-AIO-NCQ-tp5780454p5781425.html Sent from the freebsd-current mailing list archive at Nabble.com.
