Thanks for the info, I know testing this can be a pain with all the reboots. :) Well, it looks like the _dispatch_clear completes without a problem. Could you run ksymoops on the syslog? That will decode the back trace from the oops (it's best to run it right after the oops before you reboot, so you use the symbol table from the modules installed at the time of the error). I just checked in changes to do byte swapping for the DMA test and the vertex buffers. The vertex buffer changes are needed for real DMA, but this won't fix your current problem with MMIO. The DMA test should work however, so if you update from cvs and this is working, that's a good start. If it works, you should see the same 7 VERTEX_ register values in the system log before and after the test. One note about this: once a DMA pass fails, you'll need to do a cold reboot before DMA will work again. -- Leif Delgass http://www.retinalburn.net _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
