The patch works for me. echo 3 > /proc/sys/vm/drop_caches as well as rmmod radeon do not end up in a crash anymore. However, I have still no clue why one of these makes drm_open to fail. On rmmod radeon I get the following log messages. If don't know if the 'unpin not necessary' has anything to do with it. [drm] radeon: finishing device. radeon 0000:01:00.0: ffff88024e526c00 unpin not necessary radeon 0000:01:00.0: ffff88024f2f6000 unpin not necessary radeon 0000:01:00.0: ffff88024f2f6000 unpin not necessary [TTM] Finalizing pool allocator [TTM] Finalizing DMA pool allocator [TTM] Zone kernel: Used memory at exit: 0 kiB [TTM] Zone dma32: Used memory at exit: 0 kiB [drm] radeon: ttm finalized vga_switcheroo: disabled [drm] Module unloaded By the way, sometimes my r8169 ethernet controller does not survive suspend/hibernation (does not detect link). rmmod/modprobe helps. I don't know if this is related. -------------- next part -------------- A non-text attachment was scrubbed...
