Seems I got my SSD working again — I’ve created a separate post about that:
Solving (?) one type of frozen disk problem
why am I having to debug Critical level bugs alone on a relatively clean Qubes installation
That’s annoying indeed. At the same time, I think this is not because of Qubes, instead, it’s the Linux kernel, and had you been using CentOS or Debian, you’d run into the same problems, once you upgraded to the problematic kernel. — From what I’ve read, these problems happen more often with Linux than with Windows. I suppose there’s more people getting paid for & working with fixing Windows laptop problems, than Linux laptop problems.
Anyway after having seen WiFi break (that was in Ubuntu), or problems with external monitors, and now a SSD, all this following kernel upgrades (minor patches), I’m not going to recommend a Linux laptop to anyone unless they have specific needs (e.g. Qubes & security).
turned out to be a hardware error
Ok, seems as if to find out & verify that it was indeed the hardware, you had to wipe the disk and install another OS?
— I hope it’ll take long until I’ll see an actual hardware error and have to do that :- /
