Thanks, reducing the ARC to 50% seems to have done the trick.

Might look into this at some point, as I’m kind of wasting RAM with the 50% solution. But I might also just wait for an official fix and not mess with kernel stuff. Wasn’t clear from those discussions if that fix survives a reboot.

You need to add the echo command as pre-init startup command so it is performed at each boot. I’m assuming iX will change the kernel default in future so when the next update comes out you can remove the startup command.

I just applied this: echo n >/sys/kernel/mm/lru_gen/enabled and I use full RAM capacity. Guess, you can use either of the two solutions.
