This BUG halt was reported a while back, but the patch somehow got
missed:

It appears that the side effect that starts the shutdown timer was processed
multiple times, which can happen as multiple paths can trigger it.  This of
course leads to the BUG halt in add_timer getting called.

Fix seems pretty straightforward, just check before the timer is added if its
already been started.  If it has mod the timer instead to min(current
expiration, new expiration)

Its been tested but not confirmed to fix the problem, as the issue has only
occured in production environments where test kernels are enjoined from being
installed.  It appears to be a sane fix to me though.  Also, recentely,
Jere found a reproducer posted on list to confirm that this resolves the
issues

As discussed in the alternative approach
zephyrproject-rtos/zephyr#68494, k_panic() in
POSIX mode has various shortcomings that do not provide a useful
trace. Useless pointers to signal handlers or other cleanup routines are
printed instead. Leverage our already existing
k_sys_fatal_error_handler() and dereference a NULL pointer there when in
POSIX mode. This "fails fast" and provides a complete and relevant stack
trace in CI when fuzzing or when using some other static
analyzer. Example of how fuzzing failure thesofproject#8832 would have looked like in
CI results thanks to this commit:

The fuzzer engine has produced crash caused by NULL pointer read that
originated from ipc_stream_pcm_free(). The crash happens when the
pipeline of the found comp_dev does not have a source_comp and
pipeline_reset() is called for it. This commit simply adds a test
for such a situation and bails out if it is found.
