The boot0 seems swapped, it should read back 0x0d90a0a1, which would be a NVD9 (GF119) which is a very reasonable chipset for a GT610 or GT520 to report. [Unlike NV1A which is a GeForce2 IGP from ~2003 or so.] Normally we kick the card into the proper LE/BE mode (which byteswaps all the register reads/writes at the hw level), but perhaps that's not working for some reason? I assume this is a BE box, and there's not a whole lot of testing that goes on (esp for newer cards) on BE. Another thing to note is that nouveau requires 4K pages (not for any great reason, but there's a lot of confusion inside the driver regarding whether system or gpu pages are being used, and PAGE_SHIFT/SIZE aren't universally used in the right places).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
