I once ran into a very severe AHCI timeout problem. 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.
