ata power save broken in 5.3

Hi.

Somewhere around BETA7 ATA power save stopped working.

When trying to access a disk that has spun down i get the following
in /var/log/messages :
Nov  9 03:01:06 chantry kernel: ad1: TIMEOUT - READ_DMA retrying (2
retries left) LBA=575
Nov  9 03:01:07 chantry kernel: ad1: FAILURE - READ_DMA timed out

These are "normal". The server has been running with ata powersave for 3
years or so, and I've always gotten those messages when trying to access
a drive that is not spinning.

The new thing(s) are, when i access the disks again by a "ls" it shows
me the contents of each directory within the mount location, i.e. :
ls /mnt/disk1 should show :
docs/ src/ 

Instead i get a listing of each dir like i had done a "ls /mnt/disk1/*"
After this the disk runs normal again.

The other scenario is that i simply get the following when accessing the
mount point : 
mount: /mnt/disk1: Bad file descriptor

On both scenarios i get a page fault panic when rebooting the machine
(as the last thing after syncing buffers).

The first one who tells me it's because my disk is dying gets a free
"pie in the face". I've been hearing that for 3 years now, and it's
worked fine from <5.0 to 5.3-BETA6.

It _still_ works fine with 5.2.1
