Public bug reported:
A few hours after upgrading a machine serving as VM hypervisor running
OpenStack Nova + libvirt from linux kernel 6.2.0-37-generic to
6.5.0-14-generic we observed kernel traces and quick disintegration of
the system and its various processes.
While the TCP connection itself was accepted, we were unable to log in via SSH
anymore or use the console.
A hard reset was required to get the machine back up. We went back to the
former HWE kernel version, 6.2.0-37-generic, and have not observed any issues
since.
Attached is all of the kernel log from bootup to the crash - this is
where the issues started ...

Title:
Kernel traces and crash on on KVM hypervisor - refcount_t: underflow;
use-after-free and refcount_t: saturated; leaking memory --
lib/refcount.c
Status in linux-hwe-6.5 package in Ubuntu:
New
Bug description:
A few hours after upgrading a machine serving as VM hypervisor running
OpenStack Nova + libvirt from linux kernel 6.2.0-37-generic to
6.5.0-14-generic we observed kernel traces and quick disintegration of
the system and its various processes.
While the TCP connection itself was accepted, we were unable to log in via
SSH anymore or use the console.
A hard reset was required to get the machine back up. We went back to the
former HWE kernel version, 6.2.0-37-generic, and have not observed any issues
since.
Attached is all of the kernel log from bootup to the crash - this is where
the issues started ...
