Multiple users have hit this over the years (through sporadic reporting) - I ended up trying ZFS and encryption wasn't an issue there at all because I guess they don't use this device. Returning to sanity (xfs), I was able to provision a dm-crypt volume no problem on the disk, however when running mkfs.xfs on the volume is what triggers the cascading failure (each request kills a kthread). Disabling IQAT on the south bridge results in a working system, however this is not the default configuration for the distribution of choice (Ubuntu 20.04.3 LTS), nor the motherboard. I'm convinced this never worked properly based on the lack of popularity for kernel encryption (crypto), and the embedded nature that SuperMicro has integrated this device in collaboration with intel as it looks like the primary usage is through external accelerator cards. Kernels tried were from RHEL8 over a year ago, and this impacts the entirety of the 5.4 series on Ubuntu. Please CC me on replies as I'm not subscribed to all lists.
