Hello,

I'm installing guix in a recent desktop that I build (little more than a 
year). After being suggested to use latest iso on cuirass, I was able to 
install guix. The boot then hanged looking for iwlwifi firmware; someone in 
the help list suggested me to edit boot options and blacklist iwlwifi, then 
reconfigure guix once in.

I did that and now booting process hangs in a new place, "Watchdog hardware is 
disabled". I include an image of the point.

Thanks,

crodges

Could you try to edit the boot options also to

- remove the `quiet`

- possibly you may need to add `nomodeset`.

What GPU is in this machine?  On your Manjaro system, lspci or GNOME
Settings for example would show.

There are problems at least with some AMD GPUs, but this may not be
the issue.

(If it AMD turns out to be the issue, Denis 'GNUtoo' Carikli suggested
to partially fix them <https://issues.guix.gnu.org/36786#9>, while I
suggested to work around them <https://issues.guix.gnu.org/48343>.
Manjaro would not have these issues because it uses a nonfree linux
package.  But your bug may be something completely different.)

Regards,
Florian

Florian, 

Removing quiet and adding nomodeset, I was able to boot for the first time!
low resolution, but I was able to edit config.scm to add 

(kernel-arguments
 '(; https://issues.guix.gnu.org/53712#12
   "modprobe.blacklist=pcspkr,snd_pcsp,iwlwifi"))

as referenced in https://issues.guix.gnu.org/53712#13

then did guix pull and sudo guix system reconfigure /etc/config.scm

Noticed that the kernel was updated to linux-libre 5.16.20. Tried to reboot 
without editing arguments in the kernel. I got to another freeze, and clearly 
it seems to be the amd gpu, as in the new attached image. Is it possible, 
considering that this gpu has free software drivers?  

The GPU is a Radeon RX 6800 XT, which manjaro lists as using open source 
drivers.

The funny thing is that AMDGPU is not really entirely free software,
only the kernel component is, but the firmwares are not. Guix doesn't
actually package AMDGPU as far as I know, you have to use The Forbidden
Channel if you have an AMD card and want to actually use it. But also
yes, it's super buggy for me as well, sometimes it freezes, sometimes
it just glitches out.

Also IMHO this further proves my point that we need a "safe graphics
mode" boot option, see issue 54945.

Hi crodges,

On Tue, Apr 19, 2022 at 09:40:20AM -0700, crodges wrote:

I proposed removing quiet so more messages would get printed to the
screen, but your photo already shows everything.

So this is bad news.  Technically the amdgpu drivers themselves are
free software, but they require nonfree firmware, and linux-libre
removes it.

With linux-libre, there is therefore no way to use the GPU for 3D
acceleration, I believe.

In your original post, you said you succeeded in installing Guix
System with the installer image.  The installer image uses
uvesafb-service-type when amdgpu fails, so you could do the same.

See the installer’s configuration file at:

~/.config/guix/current/share/guile/site/3.0/gnu/system/install.scm

The workaround I suggested at

is a more concise way to unconditionally load uvesafb, even for
graphical desktops.  Denis’ suggestion to fix the driver is a more
proper solution but more work, if it works.  Either way you won’t be
able to use accelerated 3D with linux-libre.

I’m merging this bug with 48343.

Florian

Well the uvesafb in the installer image worked for crodges, I suppose,
so in the AMDGPU case there is no need for another boot option in the
installer image.

I’m not sure what to do about the installed system.  There are
multiple choices and all are bad.  Currently by default after install
you get a broken system unless nomodeset is added.  The other libre
options are not to use most of the expensive and powerful GPU.

Regards,
Florian

Well the issue was solved, I now have a bootable guix system. I'll consider my 
options regarding the gpu. Thank you very much florian and raingloom. I 
learned quite a few things!
