The patch was never merged. The big was closed because there was an improvement in 4.17.5, and it seems like many reports like these are just closed, and never fixed. This issue still very much exists in 4.19. Some observations: This issue gets more apparent when you have less physical memory (system less likely to unfreeze) If you have a full swap drive, and full ram, system freezes to it is force rebooted If your memory is full, occasionally the system will not freezeă…‹ If the system is swapping when not frozen, it writes more to swap then when it is frozen. If swap is being used, logging in is very slow after waking computer up. (Important processes are being swapped out) Linux OOM killer is most likely not doing its job. Windows and MacOS does not freeze when using swap. What is the difference with Linux.
