When I connect an Intel SSD to SATA SIL controller (PCI ID 1095:3114), any TRIM command results in I/O errors being reported in the log. There is other similar error reported with TRIM and the SIL controller: https://bugs.centos.org/view.php?id=5880 Apparently the controller doesn't support TRIM commands. This patch disables TRIM support on the SATA SIL controller. ata7.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0 ata7.00: BMDMA2 stat 0x50001 ata7.00: failed command: DATA SET MANAGEMENT ata7.00: cmd 06/01:01:00:00:00/00:00:00:00:00/a0 tag 0 dma 512 out res 51/04:01:00:00:00/00:00:00:00:00/a0 Emask 0x1 (device error) ata7.00: status: { DRDY ERR } ata7.00: error: { ABRT } ata7.00: device reported invalid CHS sector 0 sd 8:0:0:0: [sdb] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 8:0:0:0: [sdb] tag#0 Sense Key : Illegal Request [current] [descriptor] sd 8:0:0:0: [sdb] tag#0 Add.
