Our custom Xavier NX carrier cards work for PCIe Gen3 NVME SSDs without issue. When PCIe Gen4 NVME SSDs (e.g., WD SN770) are used, there are many errors:
“PCIe Bus error: severity=Corrected”
which may delay or prevent Xavier NX boot to Ubuntu. Our application requires NVME SSD connected to carrier card through highspeed cables/connectors.
After the Gen4 NVME SSDs booted, write and read speed did reach 4.3GB/s and 5.9GB/s.
Are there ways to suppress those PCIe error messages?
Thanks in advance for suggestions
Try to diable ASPM? Adding pcie_aspm=off to the kernel cmdline.

Adding pcie_aspm=off and pci=noaer to the kernel cmdline of /boot/extlinux/extlinux.conf seems working.
Thanks
