I'm fairly sure that it's a fairly self-contained problem -- my NV05 TNT2 M64 works fine (or at least did recently, I think I last tested after 3.10 or so). Another user's NV04 also worked OK on linux-3.9 (from <a class="bz_bug_link bz_status_NEW " title="NEW - [NV04] PROTECTION_ERROR / PROTECTION_FAULT" href="show_bug.cgi?id=68854">bug 68854</a>), although it was the Creative Labs one. However he also had the resolution issue (maxing out at 1024x768). You have one of the (infamous?) BMP v0 vbioses, may be interesting to attach it to this bug, although I sincerely doubt that is the source of the issues (before BMP v2 or so, we just ignore it entirely). Without nouveau loaded, you can get it from /sys/kernel/debug/dri/0/vbios.rom . The unfortunate reality here is that you are in posession of fairly unique piece of hardware, and that (I believe) similar HW works fine. So... it's something "funny" going on. You might try booting with nouveau.debug=debug drm.debug=14 and capturing the kernel messages from that. Perhaps something interesting will come up.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
