Bug#855003: ATA HD race conditions at boot-time
Package: linux-image-686-pae
Version: 4.9.0-1
When I booted my PC it hung at one point for 30 seconds and then resumed
booting. Here's part of the dmesg for it. Note that it happened 17 seconds
into the boot.
:
[ 0.000000] Linux version 4.9.0-1-686-pae (debian-kernel@lists.debian.org) (gcc version 6.3.0 20161229 (Debian 6.3.0-2) ) #1 SMP Debian 4.9.2-2 (2017-01-12)
<snip) Below is the first mention of ata3. Note jump from 7.0638421 sec
to ~30 sec. later:

I found a report on the Inet that finds a similar error:
<a href="http://www.smythies.com/~doug/network/hd_race/";>Linux ata hard disk access race condition. WWW.Smythies.com</a>
This error doesn't repeat so I think it's a race condition. The SATA
drive is one I installed about a couple of months ago and may have booted the PC
with it perhaps 60 times with no delay like this. However, I upgraded the
kernel to -pae perhaps a couple of weeks ago. There are now 2 HD's on my
PC, one SATA (ata30) and the other a slower PATA with a ribbon cable.
