It has the potential (and some likelyhood) to corrupt hard drives occasionally, and otherwise behave erratically at several points along the way. If you are intending to develop - great. But if you are a user (like me) who wants to use the system reliably, follow the 2.2.x revisions (currently 2.2.10). Odd minor-numbered versions of Linux are in a state of flux, and are not necessarily even going to compile (structural changes may be being distributed for driver authors to work against while drivers are worked on). Now, the ? files are not a sign of already done damage. They are harmless (created by a bug in gmc, the gnome file manager) and can be deleted or ignored. On a happier note, I checked out 2.2.10 today (use -rlinux_2_2 if you use cvs to switch branches), and built it, and the dancing pixels and other artifacts are gone (on a rev 1 G3 desktop with Rage II+, but I had the same symptoms, so maybe the same fix will help). I think 2.2.10 has the mach64 work from 2.3.6 backported into it w/o the other potential problems -- +--------------------------------------------------------------------+ | .-'''''-.
