Bug description:
CPU lockup problems have been encountered on a number of computers
running kernel 5.15 or later, but this problem could've been
introduced in an earlier version. Three of these systems are running a
light weight version of Ubuntu. The kernels that have been tested are
4.19, 5.15, 5.18, 5.19, 6.0, and 6.1. The basic setup that's running
and causing problems is a program that starts several (4+) distinct
processes and communicates with different ACM/USB concurrently. This
problem can be encountered a few minutes after starting this program
up to about a week later, but it generally happens after ~1-3 days.
When the lock up occurs, if there are the same number or fewer CPU
cores than the running number of running processes doing ACM/USB
device communication, nothing else will execute due to all of the CPU
cores being locked up until the watchdog frees things up. The longest
lockup that has been encountered was over 20 minutes! The computers
that this problem has been tested and verified to be present on are
the NUC7i5BNK, the ASRock NUC BOX-1260P, and the LattePanda Delta 3.
Although, this problem appears to be system agnostic; if kernel
version ~5.15 or later is being used, it'll likely happen if this
program is setup and run on any system when enough known ACM/USB
devices are connected to it and communicated with concurrently from
different processes. The main reason "this program" is being stated in
a broad sense is because multiple different setups fitting that
description have been tested trying to get around encountered problems
in various clever ways and this problem has persisted regardless of
what's been done.
Here's a short snippet from the LattePanda Delta 3's syslog:

The remainder of this log and the syslog from the ASRock NUC BOX-1260P are
attached.
Also, to verify that kernel version 5.15 and later contains this
problem apart from other potential USB problems, the NUC7i5BNK
computer was running a variant of this program nonstop on kernel
version 4.19 for months on an Ubuntu 18.04 without any problems. Then,
after it was updated to kernel 5.15 and nothing else was changed, the
system ran into this CPU hard lockup problem after a little more than
a day of running. Another interesting observation was that the CPU
load and usage appeared much higher and things were boggier with later
kernels. The average load on version 4.19 was ~1-2, and on version
5.15 was ~17-21+. Version 5.4 was installed and tested on this
computer to see how it would run in a quick test. Things were less
boggy and the average load dropped to ~5-7, but it still wasn't as
good as version 4.19. Although, it should be mentioned that other
things were setup and running alongside this default program so it may
not be a 1 to 1 conversion.
These computers would've been tested further on other kernel versions to
determine on what version this problem arose, but as of right now all of them
are being used for other purposes, such as trying to reproduce the problem on a
bare-bones arch install to get support from that community also.
