[SOLVED]HP dv6t Suspend/Resume Error (mei_me?)

Hello all,

Suspend and Resume isn't working on my HP dv6t... Well I guess Resume is what isn't working.  I got this message the last time I tried to resume: https://s3.amazonaws.com/pushbullet-upl … 171738.jpg
mei_me I guess is causing the problem.  Any ideas on how to resolve this?

Figured it out!  It was mei_me that was causing the problem.  I had to unbind the device which was getting hung up from it.  First you have to find out which device:

find /sys/bus/pci/drivers/mei_me/ -type l|sed 's#^.*/##'

  It will output the device address, it will look something like this:

0000:00:03.0

Then, as root you need to unbind the device you just determined from the driver:

echo 0000:00:03.0 > /sys/bus/pci/drivers/mei_me/unbind

  Now reboot and you should be good to go!

I'm sorry for my ignorance, but i'm also facing similar problems with an HP laptop.

Whenever I suspend my laptop, it will randomly freeze. Sometimes resuming works, some other times, it won't..
For further investigation, I'll try your proposed solution, but before, I'd like to know what I'm doing.

On that matter,
What exactly does unbind and bind means? Wouldn't be easier to simply blacklist the mei_me kernel module (driver)?
Does it works for you 100% of the times now? even when prolonged suspension?

Cheers,

Hey Cafe,

Unfortunately, I can't really answer your question.  I stumbled upon this solution on a blog post about kernel 3.10 and just gave it a shot.  I never tried blacklisting and the module, but I suppose that would work.  So far, it has been two days and it has resumed every time flawlessly (even after being suspended for an entire night). 

Maybe somebody more knowledgeable could shed some light on the situation?

Regards
Dan
