After getting some DRDY error messages on my physical testbench:
Code
janv. 18 20:01:00 omv kernel: ata5.00: failed command: SMART
janv. 18 20:01:00 omv kernel: ata5.00: cmd b0/d5:01:e1:4f:c2/00:00:00:00:00/00 tag 30 pio 512 in
res 40/00:01:03:00:00/00:00:00:00:00/00 Emask 0x4 (timeout)
janv. 18 20:01:00 omv kernel: ata5.00: status: { DRDY }
i fix them by deseabling the PCI IDE ONBOARD CHIP from my bios motherboard.
It may help people ...
