I rebuild the driver several times recently with and without full
debugging. Nothing is fixed yet, except that I fixed
--enable-debug=full and found
I suggest you test a littlee longer: sometimes it crashes on login,
sometimes it takes poking around. I contacted the upstream too. Please
chime in https://gitlab.freedesktop.org/xorg/driver/xf86-video-intel/-/issues/189

Well, with the current build I manage to crash within 1 minute.

The backtrace I get with the current Fedora build is the same every time, but does not involve `sna_accel_flush()`  (it crashes in `kgem_buffer_release()` down from `sna_accel_block()`)

With the scratch build, I haven't managed to reproduce, no matter what I try (x11perf, map/unmap windows programatically, etc.).

May I ask you to give https://koji.fedoraproject.org/koji/taskinfo?taskID=43188723 a try, just in case?

Cheers
