I just spent 2 1/2 hours on the phone with Apple Tech Support this morning. Here is the issue.

After putting the computer to sleep after upgrading to Mountain Lion, the computer goes to sleep and then about 5 - 7 seconds later, restarts and says there was a problem and the computer had to restart. Allowing the computer to sleep via energy settings does not create the problem. Running the computer in Safe Mode also does not create the problem.

I have confirmed that uninstalling the latest driver fixes the issue. Reinstalling it fresh recreates the issue.

Apple Tech also confirmed that the logs I sent them have numerous errors related to the DisplayLink driver and this was the prime suspect in the issue.

Here are the logs collected by your app. https://www.dropbox.com/sh/zoluv7v7g8rl9nq/v0TaiX_eeZ

I have a late 2009 iMac, 3.33GHz with an ATI Radeon HD 4670

Yes. Sounds somewhat similar. In my case it is when I put the computer to sleep, it restarts after a few seconds telling me it had to restart because of a problem. The other thread seems to be after waking from sleep is causing kernel panics

Yes, I have the same problem. Since upgrading to mountain lion and upgrading the display link driver to the latest version I can no longer let my 15 inch macbook pro (late 2011) go into sleep mode because it simply shuts down after a while and on restart it tells me there was a problem that caused the shutdown......

When my mac is not on mains power this is a huge problem and has caused me to lose unsaved work etc.....

I also have uninstalled the driver and the problem has vanished, returning as soon as I reinstalled the driver.....

Please help!

Same exact thing happening here on a MBP (Late 2010). It doesn't happen every time, but I'd say at least 50% of the time after shutting the lid and letting it go to sleep the issue happens.

When I first open the lid, I get 3-5 seconds of view of my desktop before it crashes/restarts. This did not happen before I updated to Mountain Lion and the latest driver.

As a side note, this version also still seems to have the bug where my battery drains at 2x+ the normal speed when the Display Link driver is installed and resumes to normal operation if it is uninstalled. If anyone knows how to fix that I would be grateful..

I have found the same problem with my Macbook Pro. "Upgraded" the driver, and my system now reboots after falling into deep sleep. Doesn't seem to be a problem on my iMac though. :confused:

I am also seeing the error on my MB Pro 2011 (Core i7, Intel HD Graphics 3000 512 MB + AMD Radeon HD 6770M).

A really easy way to reproduce the error is to try to dynamically unload the DisplayLink driver kext. (I hoped unloading the driver would make it easier to then put my machine to sleep)

sudo kextunload -b com.displaylink.driver.DisplayLinkDriver

I really hope the OS X driver gets the same level of attention as the Windows driver at some point, these crashes are beyond painful.

This issue is getting more frustrating.. I'm now having to restart my computer daily and have lost a few files that I forgot to save before closing the lid because the computer crashes upon waking it up.

Any idea when we will see a resolution? Is this issue affecting ALL mountain lion users, or just those of us on the Late 2010 MBP? If it helps, I installed ML just recently by using a flash drive + restoring from a Time Machine backup..

Looks to be linked to power management. Nickrouty what is your model of MBP?
We can't reproduce yet unfortunately. Has anyone tried the 10.8.1 preview? (If you are a developer).

It's interesting that the OS attempts to unload the kext, it's possible that something changed in the dependencies in 10.8. It should not be related to this issue but we'll check that.

I'm the original poster of this topic. I have an iMac. The one thing that was tried was to let the computer go to sleep via power management and it didn't cause the problem. Doing it manually did. This was only tried once so it might be worth trying with other people who have this issue and see if it works the same for them.

You might be on to something with the power management idea.

I am having the same issue. Went to apple with the issue loaded a fresh copy of M.L. (not a time machine backup) Did not reinstalled display link driver worked fine for over a week. Loaded the driver on and it is crashing again. We need a better driver please. This is beyond frustrating :mad:

Hi,

I am having the same issue and here are the details of my macbook:

15" late 2011

16GB Ram 750G HD

2.2 i7,

This happens everyday after I leave work where i use the DisplayLink, I found that crash files in my Logs folder, and OSX moved the kext file over to the Incompatible Software Directory.

Try connecting the power, display link, and the apple usb keyboard into the laptop and the apple minidisplay to analog dongle.

Remove the power, the display port adapter, and the usb outputs (basically work from power port and work you way down. You will see the macbook crash.

What sucks about this is that I would notice that my macbook would be scorching hot when I got home from work because I thought it was going to sleep.

This boils down to the crash causing my macbook to reboot and then stay stuck at the login screen while the lid was shut.

Thanks,

Just installed 10.8.1, reinstalled the Display Link driver and my computer is no longer restarting after being put to sleep.

Finally after 3 weeks...

I was getting many failures until I just turned off my second monitor. Now not only no failures for three days but everything runs faster. Is there a fix that will allow me to have both monitors running all the time?
