https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=205903 --- Comment #9 from Michael Danilov <mike.d.ft402@gmail.com> --- Created attachment 170497 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=170497&action=edit Patch to x11/nvidia-driver to CAUSE the panic. Alright, I think I have come up with a reliable way to reproduce this annoying problem. Here is a broken version of the patch suggested in https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195097 that causes (I think!) similar panic. I have fed rm_free_unused_clients null pointer only on one occasion and it crashed where I expected it to crash -- on exiting 3D programs. In that bug they suggest that "Here rm_free_unused_clients is called with a null pointer. This function is not open source, but from the panic my guess is it's not happy being called with a null pointer.", which pretty much may be the case here. STEPS TO REPRODUCE A 1. Install driver with patch applied. 2. Start a 3D program (I used Blender). 3. Exit the program. STEPS TO REPRODUCE B 1. Start X. 2. Kill X. -- You are receiving this mail because: You are on the CC list for the bug.help
