Method = 0x40. Which doesn't correspond to a valid subchan method. But in that case, I'd expect to see a INVALID_MTHD on the next word -- the command itself is still valid. (Just looking at the pseudo-code at <a href="https://github.com/envytools/envytools/blob/master/hwdocs/fifo/dma-pusher.rst">https://github.com/envytools/envytools/blob/master/hwdocs/fifo/dma-pusher.rst</a> -- perhaps it's inaccurate.) So... the mystery is where does this 0x40 method come from. There are a lot of potential culprites. Given that it's happening both to X and to some non-X process that just uses mesa, I'm going to place the blame on libdrm or the kernel... but that seems a bit far-fetched too. Dunno. As for the memory management issues, of course, anything is possible. But it shouldn't happen :)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
