Hi!

Note: There was some discussion about this on IRC a couple of weeks ago.

Guix won't boot on my ThinkPad T430 after an installation with fully
encrypted disk:

* First, at the end of the installation, I'm getting the following error
message multiple times: "device-mapper: remove ioctl on cryptroot
failed: Device or resource busy"


* On boot, I am being prompted for the encryption key. So far so good.
The Grub menu is then displayed and disappears after a few seconds – as
it should – after which the computer is stuck on the Grub background image:


* Here are the Grub commands:


* As a test, I added an echo command at the very end. It got displayed.
* It happens on both 1.0.0 and 1.0.1.
* It happens both with and without a separate home partition.
* It happens on the two SSDs I had at hand.
* It does not happen if only the home partition is encrypted.
* I also tested this in a virtual machine. The issue did NOT happen.

Thanks,
Reg

These messages are annoying but really harmless.

Weird.

Does your compute have an AMD graphics card that could lead the kernel
(KMS) to wreck havoc during initialization?

Did you have hardware-related problems with other free GNU/Linux distros
on this machine before?

Thanks,

The strange behaviour here is that you reported it does not happen if
only the home partition is encrypted: if this is true this could not be
a GPU issue.

I'm going to test a full encrypted root install on bare metal and will
report back on this

AFAIU ThinkPad T430 could come with an additional "NVIDIA NVS 5400M" GPU
[1] that is very Linux _unfriendly_; you can check this by booting
your machine as detailed below and doing a "lspci -nnn | grep VGA"

Anyway, to check if GPU is the problem here could you please add
"modprobe.blacklist=radeon" [2] (or vga=791 if this does not work [3])
to the "linux" kernel arguments and report back the error messages, if
any?

To add that kernel argument, you have to enter edit mode in Grub by
pressing "e" before the timeout (or press ESC to stop the timeout) and
edit the "linux" Grub line

If blacklisting radeon module works for you, you should add it to your
(operating-system ...) definition to make it permanent, something like:

(kernel-arguments '("modprobe.blacklist=radeon"))

HTH! Gio'.

[...]



[2] Grub configuration in the installarion ISO have that parameter

[3] should not be the case since the installer worked for you without
that kernel argument

No error message & still the same issue with both these arguments.

OK so it seems this is not related to your GPU but to disk encryption

I cannot reproduce your very same situation: I'm using a manual
partition scheme (not the guided one) since I want to presenve a couple
partitions on my HD

I was able to install and boot Guix on an encrypted BTRFS partition with
no issues, this is what the installer configured for bootloader,
mapped-devices and file-systems:

Toggle snippet (23 lines)
(bootloader
(bootloader-configuration
(bootloader grub-efi-bootloader)
(target "/boot/efi")
(keyboard-layout keyboard-layout)))
(mapped-devices
(list (mapped-device
(source
(uuid "228371e9-9cd7-4bb5-8976-d65029892b8e"))
(target "guix")
(type luks-device-mapping))))
(file-systems
(cons* (file-system
(mount-point "/")
(device "/dev/mapper/guix")
(type "btrfs")
(dependencies mapped-devices))
(file-system
(mount-point "/boot/efi")
(type "vfat"))
%base-file-systems))

I first had to insert the LUKS encryption key to let Grub start, then I
had to enter the same key after Grub booted

Please are you able to connect to ssh to your laptop during installation
(before rebooting) [1] and paste here the content of /mnt/etc/config.scm
generated by the installer?

Thanks! Gio'.

[1] you can switch to a console with CTRL-ALT-F3, set the root password
(passwd) and "herd start ssh-daemon"

On a test machine I practically have the very same bootloader,
mapped-device and file-systems configuration and I've no problems
booting

Are you sure your laptop does not boot at all? I mean: can't you switch
to a different tty (CTRL-ALT-F2) and see a console login?

I'm out of ideas here, sorry

HTH! Gio'.

Nothing happens when I press CTRL-ALT-F2, F3, ...
The only key combination that has any effect is CTRL-ALT-DEL.

Could it be that it boots but that display is completely broken?

Can you ping it or connect to it over SSH?

A friend had an issue that looked similar on an HP laptop (no
Thinkpad) in Guix System. GRUB got stuck either after entering the
encryption key or, without encryption, when booting Guix. The
resolution was to enable CSM Legacy Support in the UEFI/BIOS settings
(even though it is a grub-efi-bootloader install). Maybe this is
something to try if you or someone else has such an issue again.

Hi Florian,

Thank you very much for getting back to me! CSM legacy support was
already enabled on my ThinkPad but guess what.. *Disabling* it fixed the
problem! My computer is booting without issues now with a fully

Thank you so much!

This is nice to hear. Thank you for testing; very quick. BTW your
message did not go through to the bug report; probably it was my
mistake putting the wrong list in Cc.

Now I wonder where this should be documented. Should there be a
Troubleshooting section in the manual?

(address . bug-guix@gnu.org)
125f409c5b5d92bed3bc2c7d270f2c9e@selfhosted.xyz
Hi,
Im having this exact same issue: I can enter the password once to unlock
the disk, then after selecting the grub entry I am stuck at the Guix
grub screen.

I have used terminal based "manual" install, graphical guided install
for full disk - all on one partition - and graphical guided install with
manually created separate /boot partition.

Only non-encrypted disk works to boot install. Also, btrfs fails, ext4
works.

This is using the current 1.3 installer image.

The reason I attempted this installation is because my
full-disk-encryption installation that's a couple years old or so failed
to boot upon reboot, and I did not have any previous generation that I
could select from the grub menu that would boot either - i.e. my Guix
system broke.

I'm considering using an old 1.2 installer image, but Im not sure
whether I should just wait for a 1.4 release, or if there are other
suggestions?

And, I can't ping or ssh to the machine, after Im stuck at the Guix grub
boot screen.

If this is just me and Reg - it's weird. I mean I suppose the full disk
encryption option has been tested by someone before releasing the
installer?

What should I try next?

Best regards,
David

Can you try the latest installer iso in the meantime, the one at [1]?

Hi Josselin,

Thanks for your help with this issue. I tried ur suggestion and got the
same results. However, the comment about CSM legacy support gave me a
hint from which I managed to "solve" it: my laptop uses OSBoot, and I
always boot with the Seabios payload, but booting from the Grub
commandline without loading Seabios actually worked fine. Just never
occured to me to try it until I saw that email reply.

Thanks!

//David
