Description of problem: The sata_sx4.c driver is issuing a NODATA command using packet mode and the interrupt service routine doesn't handle the interrupt since the ATA_TFLAG_POLLING bit is set. This results in ATA_CMD_SET_FEATURES timing out and device is disabled, the driver fails in -53.el5, -92.el5, and -128.el5.
