我的dmesg每秒都充斥著以下內容（注意，以下內容永遠重複；但確切的順序似乎有所不同）：
ata15.00: failed to IDENTIFY (I/O error, err_mask=0x100)
ata15: limiting SATA link speed to 1.5 Gbps
ata15: SATA link down (SStatus 1 SControl 310)
ata15: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata15.00: failed to IDENTIFY (I/O error, err_mask=0x100)
我看到 PCI ID
# ls -l /sys/class/ata_port/
lrwxrwxrwx 1 root root 0 Dec 10 11:08 ata15 -> ../../devices/pci0000:00/0000:00:01.2/0000:02:00.0/0000:03:09.0/0000:08:00.0/ata15/ata_port/ata15
看起來（我不是 100% 相信 的輸出格式lspci）這裡相關的 PCI id/端口是08；但沒有對應的條目ls -l /dev/disk/by-path
# ls -l /dev/disk/by-path

我相信相關設備lspci -nn是
08:00.0 SATA controller: Advanced Micro Devices, Inc. [AMD] FCH SATA Controller [AHCI mode] (rev 51)
有沒有辦法收集有關此處連接的設備的更多資訊？我無法輕鬆地物理訪問機器來進行試錯。 （FWIW，我可以提供的唯一假設是這是伺服器安裝的用於手動硬碟備份的 DVDR 驅動器。）
