There was a thread[1] recently in which a Linux (specifically systemd) bug was capable of bricking motherboards. ACPI bugs can cause overheating, failure to enter sleep mode, etc. In a perfect world of open source firmware this wouldn&#x27;t be an issue, but until then the cover-your-ass behavior makes sense.<p>Does the cost of replacing a few bricked machines outweigh the reputation cost? Probably not, but it&#x27;s easy to understand the liability issues that arise from non certified OS&#x27;s.<p>[1] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11008449" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=11008449</a>
