I filed three bug reports yesterday (total count of my submitted bugs are 4 now) and I got a first fix this morning. It is actually the first code change to NetBSD repository caused by my bug report. That was fast but I hope other bugs will be fixed in less than a year contrary to my first bug report for which I made workaround myself and it is not fixed for almost 3 years. Though I don’t expect much as all of them related to specific hardware and its drivers problems. However, I am happy that my time spent on testing and debugging didn’t go wasted. If you want to fill a bug report you can use web interface for that (or NetBSD send-pr tool).
