Freeze OSX 10.6.8 (DisplayLink v1.7)

[Zillode]

Still freezes without VirtualBox drivers, added debugging information.
This time my displaylink-powered monitor didn't update anymore for 30 seconds, while the main monitor was still running fine. Then I tried to perform 'detect displays' and then both screens did not update anymore.

[Zillode]

This error log should be unrelated to power state switching.
Note: my screens were rotated by 90° in this log.

I'm having the same problems.

I just upgraded from the dynadock U (PA3575U-1PRP) to the dynadock U3.0 (PA3927U-1PRP), and I am now have the same problems Zillode reported above.

Prior to connecting the U3.0, I first upgraded my displaylink drivers from 1.6 to 1.7 (assuming I'd need it for the newer U3.0 hardware).

Well, the instant I plug in my USB cable from the U3.0 into the Mac... it freezes, and I get the dimmed screen with the message about holding down the power button to reboot.

I'm running Mac OS X 10.6.8, and under displaylink 1.6 with the older dynadock U, it worked fine! Now the new U3.0 is a brick to me.

I'm assuming (hoping) this is a bug in 1.7, and it will be fixed soon. If so, any idea when that will be?

If not, I'm gonna have to return the U3.0.

Also, I'd like to try the 1.6 displaylink driver with the U3.0. Its not on the main download site anymore. Any idea where I can get it?

Your Mac is in kernel panic, it's a different issue than Zillode.
The U3 issue is a known bug in the built-in audio drivers in Mac OS. We worked around it with later firmware but DL-3x00 devices are not yet supported on Mac so you won't be able to use the U3 right now.
Please let me know if the package or literature or website of the U3 mentioned Mac support so we can invite Toshiba to rectify it.
I'm afraid I can't comment about the release date of Mac drivers with DL-3x00 support.

Best regards,

Hi Zillode,

Well this is really annoying. I have a theory about in which area the issue might be but we need to debug it directly to find out more and we can't reproduce your issue!
I think the WindowServer is locking up.. if you can ssh to your machine I'd try to kill the DisplayLinkManager process and if that fails also kill the WindowServer process (you'll need to sudo kill).
By closing the WindowServer all applications will be terminated so not much gain over a reboot unfortunately.

You might try an uninstall/reinstall as well. If I'm correct about the nature of the problem I think that Lion should be immune from it so a possible solution is to upgrade.
I can't say much more without seeing the issue in our lab. Please let me know how this goes.

Best regards,
Carlo

I killed the DisplayLinkManager (nothing happened, display-link screen freezes, my keyboard doesn't work but my mouse pointer kept moving on my normal screen).

After killing the WindowServer I saw the rotating flower on my main screen, but nothing happened after 5 minutes

I have tried this many times before (was using different versions of 1.6 and 1.7 to try to fix this issue.

Same here - the flower was rotating with me about 15 minutes and then I restarted the whole thing because I couldn't bare waiting any longer. Damn, that was annoying. More annoying that waiting too long for getting flowers to post. Unbelievable.
