In one of the panic logs we found this backtrace:
Kernel Extensions in backtrace
com.apple.iokit.IOGraphicsFamily(2.3.4)[5D671681-D21B-3CCA-9810-B15E648C1B27]@0xffffff7f96afc000->0xffffff7f96b33fff
dependency: com.apple.iokit.IOPCIFamily(2.7)[8C9E06A4-13D0-33F5-A377-9E36F0ECC229]@0xffffff7f96aac000
BSD process name corresponding to current thread: WindowServer
This should be not-related to the DisplayLink driver, but since our kernel extension has dependency on the IOGraphicsFamily we can't exclude that our driver is the cause of the problem.
If you can easily replicate the issue, I will suggest to uninstall the DisplayLink driver and test the sequence that causes the panic. If you can't reproduce it anymore without the DL driver, reinstall it and retry once again the sequence.
Would be great if you can post the new kernel panics.
Could you please clearly describe the sequence to get the panic. We have a similar machine in our labs and we can try to reproduce the issue.
Thanks
