There's a kernel patch on the list to prevent the ban, but I'm not sure if we can apply it since Mika tells me it's got something to do with dmesg spam handling in piglit. There's another way to work around the problem by adding ~10second sleep between the iterations of these subtests. That will prevent the context ban, but it will slow down the test significantly. The reason the test actually gets stuck while trying to terminate is that it does something signal-unsafe (printf is the likely culprit) from the signal hadler, and then gets stuck in some glic malloc futex.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
