开机偶尔丢失ssd

您好！
在nx上，将emmc上的文件系统迁移到SSD后（方法：git clone GitHub - jetsonhacks/rootOnNVMe: Switch the rootfs to a NVMe SSD on the Jetson Xavier NX and Jetson AGX Xavier
），偶尔识别不到nvme，偶尔能识别到nvme。我发现开机不识别的情况下，输入lspci，打印信息是空的,dmesg | grep nvme* 如下：

lspci_erro
lspci_erro1052×248 30.2 KB

而能识别到的输入命令如下显示：
lspci_ok
lspci_ok1071×511 58.8 KB

这是什么原因导致的？出现这种情况我该如何解决？感谢！

  1. Which jetpack release?

  2. What nvme drive?

  3. Custom board or devkit?

  4. Any full text log to share instead of picture.

  5. Does lspci show out that nvme drive when error happened?

1.jetpack4.4,
2.nvme drive是系统默认的
3.Custom board
4.
dmesg-log.txt (60.3 KB)
5.lspci is null

2.nvme drive是系统默认的

->2. 我是問 nvme drive是哪家牌子,哪個型號. 不是說nvme driver.

→ 3,4,5. 如果是custom board的話麻煩你拿devkit測試同一款nvme drive測試有沒有這個問題

现在问题是在custom board上，有时候会被识别，有时候不会识别？希望能给出可能存在的原因，我们好进一步排查原因并解决！谢谢！

如果連lspci都是空的話代表這可能是硬體問題. 底層PCIe端都沒收到訊號

If even lspci is null, it means the PCIe side may have hardware problem.

你也可以試試看其他牌子的nvme看有沒有這種問題

You can also try nvme drive from different brand and see if issue is still.
