One of my disks went out to lunch for a while.  Logs below.

[784786.047673] ata4.00: exception Emask 0x10 SAct 0x7800 SErr 0x0
action 0x6 frozen

Which one is it?  The only useful thing in /sys/class/ata_port/ata4 is
the device symlink, which points at
/sys/devices/pci0000:00/0000:00:1f.2/ata4.

For example, ata2 here:

$ cd /sys/devices
$ find . -name ata2
./pci0000:00/0000:00:1f.2/ata2
./pci0000:00/0000:00:1f.2/ata2/ata_port/ata2
$ cd ./pci0000:00/0000:00:1f.2/ata2
$ ls -dl host*/targ*
drwxr-xr-x 4 root root 0 Aug 30 18:09 host1/target1:0:0

Aha!  This works on 3.5 but not on 3.2.

3.4.x here..
