I did not have the chance to see the logs but I can confirm that 6.8.0-11 is extremely unstable. It randomly but surely hangs under load.
It usually hangs at the beginning of default Ubuntu 24.04 ISO install on both KVM and Virtual box. On real H/W (Dell XPS13) it hangs under load (nothing in the logs). Sometime the UI freezes and mouse cursor continues to react, sometimes it hardlocks with 100% CPU usage on Hypervisors. I am still baffled why Canonical decided to go with 6.8 for LTS... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2056706 Title: System unstable, kernel ring buffer flooded with "BUG: Bad page state in process swapper/0" Status in linux package in Ubuntu: New Bug description: After upgrading a homelab 24.04 test machine from 6.6 to 6.8 kernel that was recently introduced, the test machine started flooding the terminal with following messages: [ 1877.712068] BUG: Bad page state in process swapper/0 pfn:58919 The process name varies and appears to be whatever is currently doing something. I installed a fresh up to date copy to see if this could be replicated elsewhere and the outcome is the same. Both of the machines are VMs running under Xen with XCP-ng, although unsure if it's related. The issue produces a notable amount of syslog entries. If left running, the system will eventually go into a state where processes get stuck and do not react to systemd control, even when there's no notable load, no memory pressure nor is the disk space low. Booted back to 6.6 kernel the issue no longer happens.
