There is no way we can do that for all the distros and kernels we support. We can also not assume responsibility for kernel network stack bugs, driver bugs, firmware bugs, you name it. Sorry, but what you ask for is plain impossible. And, the underlying assumption that your hardware and its driver is always right, and it must be DRBD that's wrong, does not hold up in our experience. Remember broken TCP checksum offloading on some Intel Gigabit cards? We will double and triple check customer's hardware as part of a support contract. We do also pinpoint individual software or hardware issues as part of support or consultancy engagements. And we try to do what we can in terms of alerting our user community to known hardware issues. And, we do have hardware partners who take part in our DRBD Certified Platform program. And that encompasses just what the name implies, complete certified hardware platforms. Which you get full cluster stack support on. But we won't put up a "certified" NIC list like you are asking for. It just makes zero sense. Cheers, Florian
