Qubes gets completely stuck few minutes into usage

[k...@karelbilek.com]

I have installed Qubes OS on my low level notebook for experimenting. It does not work.

My notebook is hp 250 G6, the processor is Intel Celeron N3060.

Except for UEFI, that I had to set up with `efi=attr=uc` xen option, installation works fine and always finishes (I tried several times already). However, after installation and initial configuration, Qubes "crashes" few minutes after boot, mouse gets stuck, nothing is responsive.

When I talked about this on IRC a week ago, someone recommended to add `ucode=scan` as xen option - that didn't work. They also recommended to update BIOS.

It took me a week to figure out how to update BIOS (since HP instructions don't work and the updater is windows-only), but I finally managed to do it, and the symptoms are still the same, Qubes gets stuck.

I also have microcode from intel website and I could somehow try to specify it to xen options - I see it could be possible from here - http://xenbits.xen.org/docs/4.2-testing/misc/efi.html - but I am not sure what exactly does "relative to location of EFI binary" means - which binary? - and which of the files in the microcode zip this is. Also I am not sure if wrong microcode is the actual reason for the error anyway.

If you tell me how, I could try to paste here some error messages (something like dmesg?), but I have little experience with debugging xen.

It's strange that installation always works, but Qubes itself always gets stuck.

This is result of `xl dmesg` - with the default xen logging levels

This is result of `dmesg` in dom0

Those are however from a state before the freeze, nothing is freezing so far. I am not sure how to capture dmesg right before the freeze; maybe some infinite loop that keeps on writing them to files? That won't help, if the CPU is stuck

I added the microcode from intel website, converted using iucode_tools, to the xen configuration (and copied file next to EFI binary) using the rescue mode on the install USB (with the help of another USB stick), and .... Qubes still freezes.

So the problem is not with the microcode.
