I guess I'll have to look for a different cause :( Thomas Edison ..."I have not failed 700 times. I have not failed once. I have succeeded in proving that those 700 ways will not work.

Yes, moving /usr/lib/vdpau away makes the kernel errors go away. Which is what I did right now. So it's vdpau (narrows it down I hope?). Furthermore, when I do that I get this message: Failed to open VDPAU backend libvdpau_nouveau.so: kan gedeeld objectbestand niet openen: Bestand of map bestaat niet (cannot open shared library: File or directory does not exist) Which makes me wonder why error messages like these get through, despite all the attempts with fprintf(stderr within Emil's patch xD yielding 0 results. > While there is video decoding HW on the NV34, it's only semi-supported; I've > disabled this support since it appears to hang my NV34 and I haven't > identified the cause.

I would love to help, but I cannot code. To this point, I have always gotten away by reading lot's of (badly written) manpages and bash scripting. If you bend with the system it will be nice to you. Never had the courage to touch a line of C code. Maybe it's time ... Is it possible to contribute after an initial phase of self study? What kind of topics would I need to get familiair with?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
