Public bug reported:
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.
