Windows 8 BSOD and Display Flickering

Hi

Thanks for the logs. I see they are taken with v7.2 M0. Also the dock you are using uses the DL-165 USB 2.0 chip, so the audio and Ethernet are not part of the DisplayLink technology.

The logs didn't show the device disconnecting from the USB bus. Were the logs captured just after this event, or is it possible the event was lost off the end of the logs? When it does disconnect, do all USB devices drop off the USB bus or is it just the displays? If it is all devices then this looks like a general USB problem and not specific to DisplayLink (as we are only the video part of the dock hanging off the USB 2.0 hub).

For issue 2, I see you are using the most recent Intel graphics drivers. We did some testing with the latest Intel drivers on their new Haswell platforms and some fixes were put into v7.2 M1 for compatibility with this driver version.

Can you confirm it still happens on 7.2 M1 and submit logs and dmp file using 7.2 M1?

Thanks

Wim
