Hello Francis Laniel, I am just looking at some crashes in some random packages, and found this nouveau issue familiar.
I guess __pthread_cond_wait_common should be able to handle a NULL for abstime - e.g. should "Block without a timeout". https://sources.debian.org/src/glibc/2.28-10/nptl/pthread_cond_wait.c/#L499 There are also some many more bugs reported that all end with these nouveau_pushbuf_kick/nouveau_pushbuf_data calls triggering that "Assertion `kref' failed.", that might be related: https://bugs.debian.org/927954 https://bugs.debian.org/929130 https://bugs.freedesktop.org/show_bug.cgi?id=91632 https://bugs.freedesktop.org/show_bug.cgi?id=98039 https://bugzilla.redhat.com/show_bug.cgi?id=1350275 https://bugs.archlinux.org/task/59057 https://bugreports.qt.io/browse/QTBUG-41242 The last one mentions as a workaround setting an environment variable LIBGL_ALWAYS_SOFTWARE=1 or QT_XCB_FORCE_SOFTWARE_OPENGL=1, maybe on of these still helps? Kind regards, Bernhard
