| Subject: ata: enable quirk from jmicron JMB350 for JMB394 |
| |
| From: "Denis V. Lunev" <den@openvz.org> |
| |
| commit efb9e0f4f43780f0ae0c6428d66bd03e805c7539 upstream. |
| |
| Without the patch the kernel generates the following error. |
| |
| ata11.15: SATA link up 1.5 Gbps (SStatus 113 SControl 310) |
| ata11.15: Port Multiplier vendor mismatch '0x197b' != '0x123' |
| ata11.15: PMP revalidation failed (errno=-19) |
| ata11.15: failed to recover PMP after 5 tries, giving up |
| |
| This patch helps to bypass this error and the device becomes |
| functional. |
