Created attachment 287561 [details] Dmesg after unplugging the SSD. Hello, I have a Lenovo C940 under Manjaro with kernel 5.6-rc2. I am using a Samsung T5 SSD USB3.1 Gen2 disk with usb C connector. If I connect the disk before booting, it will work correctly. However If I either unplug/replug it once the os booted or if I plug it after the boot then the disk won't be detected. I joined my dmesg and journalctl logs, but I did not see much information from the logs... However, by using a thunderbolt3 dock and connecting the disk to the USB A ports, I had no problem when connecting/disconnecting the drive several times. However, as soon as I was using the usb C ports, mapped to thunderbolt3, directly from the laptop or with the dock, same problems described above occurred. This problem may be linked to this ticket: https://bugzilla.kernel.org/show_bug.cgi?id=206459 I am enjoying a similar problem with my Thunderbolt 3 dock (OWC Thunderbolt3 dock) when not connecting it before the boot. It even leads to os crash, but I will fill another bug report for this particular issue. I can provide more log if required, please feel free to give me any other commands/idea to debug this. Thanks,

It seems the patch proposed here https://bugzilla.kernel.org/show_bug.cgi?id=206657 fix the problem. Will wait and test a few days before to mark it as solved.
