I've also been able to confirm that this happens with Kernel 5.16 or at least
similar bugs do such as Unable to handle kernel NULL pointer dereference,
programs such as postgresql break dramatically, and another time SSH panicked
the system with a kernel unaligned access. This happened during apt-get:
