Hi Justin, did anything ever come of this report?  Is it reproducible?
Did it seem to be related to suspend/resume?

Yes-- this turned out to be the result of the Intel i9 13900k/14900k known
CPU failure/bug issue.  After working with Intel to replace the failing
i9-14900k with a replacement unit, everything has been rock solid without
any issues yet, running the new 0x12b microcode as of 10/21/2024.  This is
the first time I have seen stack smashing/NVME errors due to a CPU failing
but that is what it was, I have not seen a single instance of this error
after replacing the CPU.

Three is a more detailed account of the issue that I posted here:
