[top posting because the information in the original message is somewhat holographic.] Thanks for your detailed report. It's hard to help when not enough detail is included. Unfortunately, you seem to have perhaps five problems and it is hard to disentangle them. - one power failure. Probably nothing you can do anything about. - "USB over current condition" How do you know this happened? Is there some indicator? Is this connected somehow with the NVMe drive? You seem to have several USB C ports: are all behaving this way? - reliably powering an NVMe drive, connected via USB C. What are its specified power requirements? What can the ports provide? USB C is a mess: one connector, several standards and options within those standards, especially with respect to power. - NVMe disk "lost its type label". I can guess what you mean, but that would be surprising: a surgicically precise failure. So much so that it is unlikely to be the only damage. Are you using GPT or MBR partitioning? Is your system booting with "legacy" or UEFI? - NVMe drive partitions mounting in /var/run If this isn't where you've told them to mount (via /etc/fstab?) then perhaps the partions' UUIDs have been damaged. I would think that the key to getting anywhere is to separately address each problem. Of course you cannot do that in just any order. I suggest the order in which I've listed them: each problem should only depend on the ones above.

This appeared to be related to the MB front panel | connection and at first I thought that somehow a surge made it through the | UPS and had toasted the motherboards own front port connection. This turns | out not to have been the case. It’s what happened next that puzzles me tho. | | I have an external NVME enclosure with a PCI-e X4 512 G M.2 storage which I | have been tinkering with. After disconnecting the front ports on the MB | and, I do have a PCI-e 5 port card with 4 x A + 1 Type-C connectors, which | I had configured to provide four more front ports, with two of them Type-C. | NB I don’t have the supplemental power connected as I was anticipating only | to use these ports to use data, for the time being. (This is part of what | makes me think the voltage demand reporting might be the culprit) | | When the front adapter is plugged in this also isolates the Type-C port on | the actual PCI-e card from being used. After I removed all connections from | that card and I plugged my M.2 device into the motherboard’s one Type-C | port the system turned off like a light switch, no hang, just off. | | After much fooling around, starting with connecting the keyboard and mouse | to the onboard legacy USB 2.0 slots, I’m sort of back where I started. The | two stock USB 3 front ports are connected and working. The supplemental | front ports are connected to the expansion card and working, sort of, | Type-A works, Type-C does not. | | Connecting the device, if I connect using a cord adapter to Type-A, the | mounts show up in /run/media. It is configured as a boot device. At first I | thought the over current was related to the fact that that particular cord | adapter is 3 ft long, but I’m rethinking that although consistent power | negotiating and impedance seem to be part of the problem. | | What did happen was that the M.2 drive had lost it’s type label and I | thought I did the right thing by using gdisk to relabel the volume, but now | it shows up as W95 Ext d (LBA). Also, gparted now shows a libparted error | for the actual volume I am currently booting from, although gnome-disks is | fine with it. | | Perhaps the libparted error is related to my kernel version and non | complementary libparted updates. I have seen this as an old issue of out of | but I cannot so far consistently switch from connecting the device via Type | A and Type C connections. Maybe this is a memory hangover concerning the | voltage requested by Type-A vs Type-C | | | My current kernel. | | Linux archon 5.8.8-100.fc31.x86_64 #1 SMP Wed Sep 9 20:29:23 UTC 2020 | x86_64
