Recently Linux Support Forum was merged with Drivers & Software branch -- strange decision (in order to hide absence of real support from AMD team? ), but ok. However, why posts with recent responses are not shown in the "Recent Content" of the "Drivers & Support" (for example, this)?
Search "Linux" shows many posts.
But if Linux is not in title post(forum search), yes , is hard to find other posts.
Maybe include Linux in title from now on(or bookmark).
Understand your frustration in looking for older posts. More info on site changes would be nice.
