But I'm not entirely confident in that result ATM. Among other things I had set ZSWAP_DEFAULT_ON for 5.7, and I had zswap configured but not active previously, so that could be it too. I'm not typically under enough memory pressure to trigger it, but... Luckily a git show -R generated patch still applies cleanly on current master (5.7.0-rc4-00029-gdc56c5acd, tho I've only built it not rebooted to test it yet) so I can test both the commit-revert patch and the changed zswap options now. So I'm confirming still. But perhaps take another look at that commit and see if there's some way allowing unlimited VM_FAULT_RETRY could leave drm at least on on amdgpu eternally stalled, which does seem to fit the symptoms, whether it's unlimited VM_FAULT_RETRY or not. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
