Description of problem:
Since kernel 3.3.0-4.fc16.i686 I have found that during boot, and also when resuming from hibernate this message appears on screen (and also in /var/log/messages) with a pause of a couple of seconds before and after:
  ata2: link is slow to respond, please be patient (ready=0)

Version-Release number of selected component (if applicable):
Fedora 16 kernel 3.3.0-4 (fixed a bug that caused pm-hibernate to crash often).

How reproducible:
Happens always during boot, and most times during resume from hibernate.

Steps to Reproduce:
1. boot, or resume from pm-hibernate
(I use runlevel 3 - so do not enter graphical mode during booting and only at a very late stage during resume. People who start in graphical mode may not see this problem, unless they look in /var/log/messages. It will nevertheless add several seconds to time for boot/resume.)

2. Watch screen, just before resolution changes to high resolution.
3.
  
Actual results:
Typical entries before and after this in the messages file look like this:

Expected results:   Should not pause. Did not pause in earlier versions of f16 kernel.

Additional info:

This happens on Dell Latitude E6410 laptop:

I've used smartctl to test my hard drive and found no errors.

I can live with this, but thought I should report it in case it is a bug that should be fixed.

Google shows that "COMRESET failed (errno=-16)" is mentioned in several queries and bug reports in older versions of linux. I have checked my 'messages' files on the E6410 going back to January 2012 and find no sign of this before kernel 3.3.0-4.fc16.i686
