[Bug 301353] Re: HP Pavilion dv5: ATA exception on resume from suspend

[Paul Swanson]

Attention owners of dv5's and other affected models: Tired of owning a
gorgeous laptop that won't wake up? Here's what YOU can do ...

I propose we make a group effort to get HP to fix this!

If you have been following the discussions on the Linux Kernel bug
report you'll notice the prevailing view is that this is most likely a
HP BIOS bug. In this post alone we have seen other HP models cured of
this same problem through a HP BIOS update. To date this has not been
the case for the dv5 and other affected models.

I know HP doesn't officially support Linux on this model HOWEVER a
faulty BIOS is just that, a faulty BIOS, and it should be fixed
regardless of whether it affects the supported OS or not. If you can
prove to HP that this particular piece of firmware is flawed and that
there is a good number of effected customers then maybe ... just maybe
... someone at HP will do the right thing. After all, we can only live
in hope!

I propose we make a group effort to contact HP support in a respectful
but persistent manner so that our request might be heard by someone in
their firmware coding department and tended to. Here is the worldwide HP
support directory:

Here is a suggested message to send to support (if you have a more
persuasive version please contribute!):

Dear HP Support Person,

I am the owner of a HP dv5 laptop and I have learned that my firmware
has a bug which is causing me some big problems. My laptop will suspend,
but when it wakes up the hard drive will not reactivate so I need to
reboot. You can imagine how much of a pain this is on laptop!

I prefer to use a version of Linux on my laptop, and I understand that
you don't support Linux, but I have discovered that there are many other
people in my position and through a careful community effort we have
been able to determine that a bug in the HP firmware is most likely to
blame.

Unfortunately the HP firmware isn't open source like our operating
system so we can't fix it ourselves, and I know that you aren't obliged
to help with Linux, but here's what you can do; please pass on this
information to your BIOS firmware team so that they can assess our
claims for themselves. If I am wrong, so be it, you won't hear from me
again about this.

So that you can see how we've how been able to determine this, please
have a look at the following links:

The Linux Kernel bug report: http://bugzilla.kernel.org/show_bug.cgi?id=12276
The Ubuntu bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/301353 (as you can see there's a lot of us)
The ATA driver: http://ata.wiki.kernel.org/index.php/Known_issues (they are now recommend that user not buy HP laptops)

The dv7 was cured of this very same problem by firmware update F21, but
the recent updates for my dv5 have not done so.

Please, I really like my laptop and I need this problem fixed. Your
consideration would be greatly appreciated!

Sincerely,

I know some of you have already done this, but I think some solidarity
on this might go further towards getting something done.

Thanks!!

** Description changed:

  On resume from suspend in Ubuntu 8.10 (Intrepid Ibex) the ATA driver
  throws a series of exceptions, as a result the filesystems can not be
  accessed and the computer needs to be rebooted. Hibernate, however, does
  work and does not have this problem, suspend / resume only. The linux
  kernel version is the latest 2.6.27-7.
  
  * Update 16th of May 2009 * The problem remains unchanged under Ubuntu
  9.04 (Jaunty Jackalope).
  
  The initial error message on resume is:
  
  btusb_intr_complete: hci0 urb f7d94a00 failed to resubmit (2)
  ata2: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4
  ata2: irq_stat 0x00000040, connection status changed
  ata1: exception Emask 0x10 SAct 0x0 SErr 0x0 action 0x9 t4
  ata1: irq_stat 0x00000040, connection status changed
  sd 0:0:0:0: rejecting I/O to offline device
  PM: Device 0:0:0:0; failed to resume: error 65536
  
  Then, as nothing is able function properly, the most repeated error
  message is as follows:
  
  ata1: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
  ata1: SError: { DevExch }
  ata2: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
  ata2: irq_stat 0x00000040, connection status changed
  ata2: SError: { DevExch }
  
  There are a variety of other error messages thrown about ext3 file
  systems not being to be re-mounted, but I haven't been able to capture
  those yet.
  
  I'm running a fresh copy of Ubuntu 8.10 (Intrepid Ibex), with the latest
  updates, on a reasonably new HP Pavilion dv5 (1075er) notebook.
  
  Rationale:
  
  Originally I posted my problem under bug #158050 but later I realised
  that this was for an older kernel version. Then I thought that bug
  #273323 would be a better fit, but that has since digressed into a KDE
  discussion, entirely irrelevant to my problem. I've looked at every
  Intrepid suspend / resume bug listed and none are specific to my
  distribution version, kernel version or hardware so I'm starting a new
  one.
  
  * Update 16th of May 2009 * There has been a Kernel Bug Report open on
  this for some time now http://bugzilla.kernel.org/show_bug.cgi?id=12276
+ 
+ * Update 18th of May 2009 * There is also evidence, anecdotal and
+ otherwise, to suggest that the same problem is present on HDX and some
+ other models of HP laptop.
