[問題] kernel錯誤訊息ata2對應的裝置
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
0x4000000 action 0xe frozen
Jul 24 03:44:35 localhost kernel: ata2: irq_stat 0x00000040, connection

Jul 24 03:44:35 localhost kernel: ata2: SError: { DevExch }
Jul 24 03:44:35 localhost kernel: ata2: limiting SATA link speed to 1.5 Gbps

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！
