| Subject: usb-storage/SCSI: blacklist FUA on JMicron 152d:2566 USB-SATA controller |
| |
| From: Dmitry Nezhevenko <dion@dion.org.ua> |
| |
| commit bf5c4136fa5ce471bdbf4cf59a813e32755fd014 upstream. |
| |
| It looks like FUA support is broken on JMicron 152d:2566 bridge: |
| |
| [223159.885704] sd 7:0:0:0: [sdc] Write Protect is off |
| [223159.885706] sd 7:0:0:0: [sdc] Mode Sense: 47 00 10 08 |
| [223159.885942] sd 7:0:0:0: [sdc] Write cache: enabled, read cache: enabled, supports DPO and FUA |
| |
| [223283.691677] sd 7:0:0:0: [sdc] |
| [223283.691680] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE |
| [223283.691681] sd 7:0:0:0: [sdc] |
| [223283.691682] Sense Key : Illegal Request [current] |
| [223283.691684] sd 7:0:0:0: [sdc] |
| [223283.691685] Add. Sense: Invalid field in cdb |
| [223283.691686] sd 7:0:0:0: [sdc] CDB: |
| [223283.691687] Write(10): 2a 08 15 d0 83 0d 00 00 01 00 |
| [223283.691690] blk_update_request: critical target error, dev sdc, sector 2927892584 |
| |
| This patch adds blacklist flag so that sd will not use FUA |
