--- Comment #10 from MirceaKitsune sonichedgehog_hyperblast00@yahoo.com --- I was able to use parallel SSH sessions to monitor changes in the files suggested by Max Staudt, which I did by using the command:
watch -n 1 cat filename
The relevant files that existed and I was able to watch are:
/sys/kernel/debug/dri/0/clients /sys/kernel/debug/dri/0/gem_names /sys/kernel/debug/dri/0/radeon_gtt_mm /sys/kernel/debug/dri/0/radeon_vram_mm /sys/kernel/debug/dri/0/ttm_dma_page_pool /sys/kernel/debug/dri/0/ttm_page_pool
I will attach the captures of each output, each showing its file <= 1 second before the freeze. I understand those files should retain information about VRAM, which indicates whether this could be a progressive memory leak.
Very important note: It has taken me hours to obtain those outputs, and for a while I thought the freeze was fixed by an update altogether. For over 2 hours I was able to run all game engines that produced this crash without getting any freeze whatsoever, which has never happened before! However the freeze returned after I restarted my machine, meaning it's still present. I have no idea whether there's a switch in my system that causes it to happen only sometimes, but hopefully those files will say something.
