sata_sx4: ata_cmd_set_features time out resulting in disabled device
Last modified: 2009-09-02 04:56:39 EDT
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.
