<p class="MsoPlainText">The batch buffer contains 3D render commands and data from glxdemo (or glxpixmap). The GPU hangs at address 0x64. That means all commands in batch buffer are completed but GPU is waiting for some flushes to finish in the pipe_control
command. Could you help me figure out is there any thing wrong in this command sequence from the ring buffer?
