My Librem 13 v4 laptop from Purisim stops booting after the decryption of the SSD. That’s what is written on the screen:

There ate thread in this forum with similar problems, but they seem not to fit for my problem. In Failed to load DMC firmware (more info requested) it is just a “blob-warning” and can be ignored. Hm, but I can not boot… And in Firmware failed to load it seems to be an SSD issue. But the last post suggest to start a rescue Linux from an USB-stick and install an ISO-image of PureOS. Could that really the solution for my problem?
Has this computer ever booted? If so, when it booted, did it produce the blob-warning?
It is possible that the blob-warning is a red herring and the blob-warning message just happens to be the last message output before something went wrong.
I wouldn’t install anything at this stage. However whenever any computer has a problem booting, it is always a good idea to do a test boot from known good external media (such as a USB flash drive that you have booted from previously). That may then fault isolate.
I’m not sure, where to find it. In the boot options menu I can select PureOS_GNU/Linux_[/vmlinuz-4.19.0-5-amd64]. In the PureBoot menu I can’t find any version- or system-information
kieran / MrChromebox:
Has this computer ever booted? / what did you do or change recently? / any OS updates installed?
I got the laptop from the it department of my employer. It was ordered by a former colleague. First there was a small screen problem (a stripe), and the laptop was send back to Purism. As the laptop came back the screen was ok, but the colleague left in between the company. The IT department tried to make a factory reset / reinstalling PureOS - but with no luck.
Yes, once it booted. But I do not know exactly what happened since then.

I can boot from a USB flash drive with a Lubuntu. There I checked the partitions with fsck: Everything is ok.
then it’s pretty old. I would update for sure and then see if the issue persists. There’s no need to persist the serial via the script, since it’s done automatically when updating via the Pureboot menu option. But the script shouldn’t be failing either, so I’ll take a look at that
Now I updated the firmware (with corboot_util.sh I got pureboot-librem_13v4-Release-15.rom). I applied it successfully. But still the boot is interrupted: Now I have two more lines:
[ 0.935811] DMAR: [DMA Read] Request device [00:02.0] fault addr 85c4db000 [fault reason 06] PTE Read access is not set

So just the two lines with [sdc] are new … but are they any useful information?
After a second boot, the [sdc] lines are vanished.
Before the firmware update the boot stops at first always in the BIOS menu of PureBoot. But now the boot goes through - unless I interrupt by pressing a key.
The BIOS has now a “System Info” entry :
Librem 13 v4
FW_VER: PureBoot-Release-15
Kernel: Linux 5.4.69-PureBoot
CPU: Intel Core i7-7500U @ 2.70GHz
RAM: 32 GB
Disk /dev/sda: 233 GB
Disk /dev/sdb: 233 GB
With the Lubuntu-System from USB I tried to find hints in the system logs. My Idea: If there is a firmware- or hardware-problem, there should also Lubuntu have problems - even it can handle them obviously better, since it can boot.
I found “things”, but I am not sure that they are related. Better would be to access the system logs of PureOS - but as far as I see, they are hidden in the crypted SSD. Is there a way to access them?
Here is what I found in the Lubuntu-logs:
kern.log:

Any more ideas what to do, to get the laptop running again? Send it back to Purism?
