Oh dear. That's using glamor on a nv30 (or nv40) board. The nv30 driver is ... erm ... imperfect. And looking back at the first comments, the Quadro 1500M appears to be a G71, and the 6600LE is obviously some nv4x as well. In which case these issues are just as likely to not be caused by the multithreading stuff at all. But you're in (limited) luck - I have a NV34 plugged in. If you can send me an apitrace I can replay to cause this to happen, I can investigate [and the NV34 doesn't support as much stuff as a NV4x, but I can fake it]. I'll also stare at the nv30_resource_copy_region code to see what it's missing.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
