From: "Denis V. Lunev" <redacted> Without the patch the kernel blames about 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.
