kernel crash (random but short time)

[joe-mojo]

I got akvcam working, and I tested video ouput and video capture. ffmpeg/ffplay example from the wiki is working nicely and I can see the virtual capture device with softwares like Cheese. BUT While not writing to ouput device nor reading from capture device, I got kernel crash (Ubuntu 20.04.1, Linux 5.4.0-53-generic). This happens at random times, but very quickly. Here is a sample trace :

Beside akvcam being loaded, the log does not show nothing related to akvcam and it looks like a crash in your graphics driver, not sure, maybe try loading the module with loglevel=7 and let see if it gives more information. Also just in case, do you have Pipewire running in background? if not, run Cheese, close it and then terminate or kill Pipewire process and check dmesg.

[hipersayanX]

I won't discard at all this is an akvcam bug, but I'm missing akvcam log, and that dmesg log is totally useless because is not pointing anywhere in akvcam source code. If no more information available I'll close this issue.

[joe-mojo]

Sure, I will provide this ASAP.

[hipersayanX]

I was not able to reproduce this specific bug, but I've found some race conditions when testing in Arch that did not appeared in Ubuntu running in VirtualBox, causing other modules to fail like that.
