Hello,
I’m running darktable 4.4.2 on EndeavourOS (a rolling arch distro):
[andrew@andrew-desktop darktable]$ darktable --version
this is darktable 4.4.2
copyright (c) 2009-2023 johannes hanika
https://github.com/darktable-org/darktable/issues/new/choose
compile options:
bit depth is 64 bit
normal build
SSE2 optimized codepath enabled
OpenMP support enabled
OpenCL support enabled
Lua support enabled, API version 9.1.0
Colord support enabled
gPhoto2 support enabled
GraphicsMagick support enabled
ImageMagick support disabled
libavif support enabled
libheif support enabled
libjxl support enabled
OpenJPEG support enabled
OpenEXR support enabled
WebP support enabled
When I enable OpenCL support in darktable, processing speeds up noticeably. However, after a few moments, the entire desktop freezes (not just a darktable crash), goes black, and the system reboots itself.
Here is the output of clinfo:

Nothing further is written on stdout when it crashes.
Is there any other debugging I can enable that might help?
It seems that the crashes mostly occur while loading images. I’ve basically been leaving OpenCL off until I’m ready to export, then just enabling it for the export process. It hasn’t crashed during export. Obviously I’d like to leave it on all the time.
