Please run this command:

  dmesg > dmesg.txt

and attach 'dmesg.txt' here.

[Daniel van Vugt (vanvugt)]

Thanks. It looks like a security feature of the Ubuntu Linux kernel blocking the driver from loading. Hopefully a kernel person can help.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1748972

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

You could sign the kernel module yourself or disable secure boot, otherwise the module won't load ->
