The Linux-Hardware.org database has been divided recently into a set of databases, one per each Linux distro. You can choose your favorite Linux distribution on the front page and hide probes and information collected from other Linux distributions.
Anyone can contribute to the database with the help of the hw-probe command:
hw-probe -all -upload
Hardware failures are highlighted in the collected logs (important SMART attributes, errors in dmesg and xorg.log, etc.). Also it's handy to search for particular hardware configurations in the community and review errors in logs to check operability of devices on board (for some devices this is done automatically by hw-probe — see statuses of devices in your probe).
Hardware stats and raw data are dumped to several Github repositories: https://github.com/linuxhw
Thanks to all for attention and new computer probes!
