Thanks! The patch does not fix the issue but it helps. Means I still get to see the 'kswapd0: page allocation failure' in the dmesg, a 'stress-ng-vm: page allocation failure' later on, another kswapd0 error later on, etc. _but_ the machine keeps running the workload, stays usable via VNC and I get no hard crash any longer. Without patch kswapd0 error and hard crash (need to power-cycle) <3min. With patch several kswapd0 errors but running for 2 hrs now. I double checked this to be sure. The patch did not apply cleanly on v6.9.3 so I applied it on v6.10-rc2. dmesg of the current v6.10-rc2 run attached. Regards, Erhard
