Where is the best place to write about bugs in Linux kernel modules?

Question

linux

The fact is that I don’t really understand where you can write about a bug that the developers could simply not catch so that they read it. Who exactly is the author of the module is not clear, the sources say that Red Hat, but I did not notice the name / email of the author.
I will be more precise. As some may know, in the kernel from the 34th branch there is a vga_switcheroo module responsible for switching hybrid graphics, there was even an article about it on Habré. So, the module is universal and covers a wide variety of hardware bundles, so in the first versions the module worked fine only in the intel + ati radeon bundle. It worked relatively well, although not without difficulties, in the 35th branch for the i915 + g210m bundle. In the 36th branch, bugs with freezes appeared in his work.
In the 37th and 38th branches, random bugs turned into a permanent core deadlock. I don’t know how to debug it, what could be the problem is not immediately visible. The problem is not only mine, it has been flagged in several threads on various forums and mailing lists, but not a single message has been answered. The kernel tested both vanilla and Ubuntu.
In general, to the point - what needs to be done so that the message reaches the author with the greatest probability, whoever he is? The error is critical and very unpleasant

Answer 1

If you use Ubuntu - then write on the launchpad. help.ubuntu.com/community/ReportingBugs They will figure it out there themselves and send it to the bucketmen, gnome eaters or firefox.
If Debian - then www.debian.org/Bugs/
And yes, judging by the description of the problem - it is only in Ubuntu. I encountered it myself =) I could not reproduce it in Debian.

Answer 2

it is most correct to write to the address indicated at the end of the module sources in such lines , it is also worth sending a copy to the mail lists of the developers of this very module, it is usually not difficult to find the mail list by soap of the author of the module.
MODULE_LICENSE("GPL v2");
MODULE_AUTHOR("Vasya Pupkin <[email protected]");
MODULE_DESCRIPTION("some kernel driver");
