Hi all,
This is my first message to the list and I don't know if that's the place t=
o report the error I'm facing...
I'm using an old mesa 20.3.1 version and sometimes I get a SIGSEGV doing sw=
ap buffer. The traces I get on GDB are:

Printing the fence var in adgpu_fence_wait I see:
(gdb) print *(struct amdgpu_fence*)fence
$7 =3D {reference =3D {count =3D 0}, syncobj =3D 0, ws =3D 0x0, ctx =3D 0x0=
, fence =3D {context =3D 0x0, ip_type =3D 67108864, ip_instance =3D 1442840=
582, ring =3D 1140850688, fence =3D 6196953087261802496}, user_fence_cpu_ad=
dress =3D 0x44000000,
submitted =3D {val =3D 0}, signalled =3D 0}
then the line
if (amdgpu_cs_syncobj_wait(afence->ws->dev, &afence->syncobj, 1,
abs_timeout, 0, NULL))
return false;
is throwing a SIGSEGV because afence->ws is a NULL pointer.
Is it a know bug already reported and solved? I need to update to a more re=
cent Mesa3d version?
Thanks a lot
Jorge
