Request device [00:1f.2] fault addr caa40000和by-path的渊源猜测

首先让我们来查看一下/dev/disk/by-path的目录到底有何古怪:
root@ubuntu:/dev/disk/by-path# ll
总用量 0
drwxr-xr-x 2 root root 200 2014-11-30 18:18 ./
drwxr-xr-x 5 root root 100 2014-11-30 18:18 ../
lrwxrwxrwx 1 root root   9 2014-11-30 18:18 pci-0000:00:07.1-scsi-1:0:0:0 -> ../../sr0
lrwxrwxrwx 1 root root   9 2014-11-30 18:18 pci-0000:00:10.0-scsi-0:0:0:0 -> ../../sda
lrwxrwxrwx 1 root root  10 2014-11-30 18:18 pci-0000:00:10.0-scsi-0:0:0:0-part1 -> ../../sda1
lrwxrwxrwx 1 root root  10 2014-11-30 18:18 pci-0000:00:10.0-scsi-0:0:0:0-part2 -> ../../sda2
lrwxrwxrwx 1 root root  10 2014-11-30 18:18 pci-0000:00:10.0-scsi-0:0:0:0-part5 -> ../../sda5
lrwxrwxrwx 1 root root   9 2014-11-30 18:18 pci-0000:00:10.0-scsi-0:0:1:0 -> ../../sdb
lrwxrwxrwx 1 root root  10 2014-11-30 18:18 pci-0000:00:10.0-scsi-0:0:1:0-part1 -> ../../sdb1
lrwxrwxrwx 1 root root  10 2014-11-30 18:18 pci-0000:00:10.0-scsi-0:0:1:0-part2 -> ../../sdb2

让我们分离一下pci-0000:00:10.0-scsi-0:0:1:0-part2
得到:00:10.0,何其相似与[00:1f.2],是否暗示了其中PCI接口的异常检测呢??
引出如下的问题PCI之间的插槽是如何定义的??
