Both errors are logged at every boot, and the drive otherwise works normally: pci 0000:bf:00.0: DOE: [500] failed to cache features : -5 pci 0000:bf:00.0: DOE: [500] failed to create mailbox: -5 So the firmware update did not change it. As the mailbox never answers, would a quirk which skips DOE discovery for this device be acceptable, instead of the two errors at every boot? Mitar
