I got a seemingly random nvme data transfer error on my new arm64 Ampere Altra machine, which has a Samsung PM1735 PCIe AIC NVMe drive. Since it's a new drive and smartctl doesn't show any errors I thought it might be worth mentioning here. I'm running 14.0-CURRENT FreeBSD 14.0-CURRENT #0 main-n263139-baef3a5b585f. dmesg contains: nvme0: WRITE sqid:16 cid:126 nsid:1 lba:2550684560 len:8 nvme0: DATA TRANSFER ERROR (00/04) crd:0 m:0 dnr:0 sqid:16 cid:126 cdw0:0 (nda0:nvme0:0:0:1): WRITE.
