dnw is a download tool for ARM. Maybe secbulk is it's driver. I don't know much about it. Any help would be appreciated. Thanks!

Need help for same.

Hi,

Even I am having "module verification failed: signature and/or required key missing - tainting kernel" error in my dmesg stack trace.

I am newbie for linux and have no idea what does it mean and how to fix it.

Did you resolve your issue? Can you share the solution with me?

Thanks.

Hi,

I got the solution for my problem.

Include library "linux/init.h" in your module i.e. #include<linux/init.h>

It worked for me.

"uname -r" must equal to "ls /usr/src/kernels/". This is how I solve the problem. My English is so bad, I don't know whether You understand what I said or not.

vboxdrv: module verification failed: signature and/or required key missing - tainting kernel

I realize that the original post is over a year old but I am having the same problem with VirtualBox. dmesg: vboxdrv: module verification failed: signature and/or required key missing - tainting kernel

VirtualBox appears to function properly but I sure don't like this error. I've done a fair amount of searching to no avail. I suppose I will post a new message and see if I can get any decent fix suggestions.
