Hi,

thanks for the output. Looks like everything is OK there; no obvious
problems which could give me a hint to your system freezes.

I have one other thing I'd like you to test. It goes back to this bug
description:

http://devgurus.amd.com/thread/159139

Seems that AMD compilers had or have an issue with atom_cmpxchg, which
darktable uses in bilateral.cl (and only there).

You can do the test within your current darktable installation, no need
to re-compile. Here are the steps:

1) find out, where file bilateral.cl is stored on your disk. We are
looking for bilateral.cl from your darktable installation, not from the
darktable sources! Likely it's in
/opt/darktable/share/darktable/kernels/ or /usr/share/darktable/kernels/.

2) go there and make a backup copy of bilateral.cl:

   cp bilateral.cl bilateral.cl.sav

3) edit bilateral.cl and search line 60

4) insert the following line just before the line with the "do" statement

   val=val+(get_local_id(0)&0xff000000);

5) save your changes in bilateral.cl and re-run darktable


Please see if things improve and report back. Afterwards you can go back
to your original bilateral.cl:

   mv bilateral.cl.sav bilateral.cl
