It looks like you’ve already done some good debugging. The issue you’re seeing really does line up with the known kernel bug related to swap files on btrfs. Since you’ve already confirmed the patch (f3a5367c679d...) isn’t included in your current kernel version, the most practical short-term workaround is what you’ve already done: disable swap on btrfs.
Two options moving forward: 1- Move your swap to a separate partition (non-btrfs) to avoid hitting this bug. 2- Install a newer kernel (from mainline builds or when Ubuntu backports the patch) where this fix is included. Also, just like I use tools such as Youtify to test and compare versions of apps across devices before updating ( recently tried it on PC from https://youtifymod.com/for-pc ), you could do something similar here by testing with the mainline kernel to confirm whether the patch solves your issue before Ubuntu integrates it. That way you’ll know for sure if it’s fixed upstream. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2080039 Title: Kernel BUG: Bad page state in process kswapd0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2080039/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
