I still experience regular instances where Darktable stalls on Debian.  I
have experimented with or without opencl.  It does not seem to make any
difference regarding this problem.

I see the following on top while Darktable hangs:

In the ~/.config/darktablerc

grep opencl .config/darktable/darktablerc
opencl=TRUE
opencl_async_pixelpipe=false
opencl_avoid_atomics=false
opencl_checksum=883356682

opencl_omit_whitebalance=
opencl_size_roundup=16
opencl_synch_cache=false
opencl_use_cpu_devices=false
opencl_use_pinned_memory=false

[sql] prepare "UPDATE images SET width = ?1, height = ?2, maker = ?3, model

focus_distance = ?10, film_id = ?11, datetime_taken = ?12, flags = ?13,

longitude = ?18, latitude = ?19, color_matrix = ?20, colorspace = ?21,
raw_black = ?22, raw_maximum = ?23 WHERE id = ?24"

This was the last message when it stalled just now.
