kernel錯誤訊息ata2對應的裝置 - Linux

我的/var/log/messages裡

三不五時就會出現這樣的訊息

Jul 24 03:44:35 localhost kernel: ata2: exception Emask 0x10 SAct 0x0 SErr

我找到了這篇

http://0rz.tw/vgks3


於是我用find /sys/ -name unique_id -exec cat {} \;

發現


/sys/devices/pci0000:00/0000:00:06.0/0000:06:00.0/host1/scsi_host/host1/

路徑下的unique_id內文為2

照這個網頁看來

ata2似乎應該在0000:06:00.0上


lshw顯示0000:06:00.0的資訊為

*-storage
description: SATA controller
product: JMB362/JMB363 Serial ATA Controller
vendor: JMicron Technology Corp.
physical id: 0
bus info: pci@0000:06:00.0
version: 03
width: 32 bits
clock: 33MHz
capabilities: storage pm pciexpress ahci_1.0 bus_master cap_list
configuration: driver=ahci latency=0
resources: irq:19 memory:feafe000-feafffff


但我用ls -l /sys/block

看起來沒有任何一顆硬碟是在0000:06:00.0上


請問我的查詢方式哪裡有誤嗎

要如何才能進一步了解ata2到底是誰


感謝！
