I observe the same issue with Sandisk Corp WD Black SN750 / PC SN730 NVMe SSD WDC PC SN730 SDBQNTY-512G-1001 After reading https://forums.unraid.net/topic/121146-nvme-aer-corrected-error-und-pcie-bus-error/ I added nvme_core.default_ps_max_latency_us=0 to the kernel command line and this seems to work around the issue for me.
