On `kexec` black screen

Question

On `kexec` black screen

Closed this issue 3 months ago · 31 comments

Hi,
I would like to install NixOS using nixos-anywhere on a mini pc with an Intel N5100.

I have tried to install starting from Fedora 39 and NixOS (via iso), using from a another machine:

nix run \
    github:nix-community/nixos-anywhere \
    -- \
    --flake .#htpc \
    --print-build-logs \
    --debug \
    user@ip

But just after the lines:

+ kexecSyscallFlags=--kexec-syscall-auto
+ /root/kexec/kexec --load /root/kexec/bzImage --kexec-syscall-auto --initrd=/root/kexec/initrd --no-checks --command-line 'init=/nix/store/fpwr9bsdi8ddizn0j9ijhy1gp7yak3m7-nixos-system-nixos-24.05pre-git/init console=tty0 console=ttyS0,115200 loglevel=4'
+ echo 'machine will boot into nixos in 6s...'
machine will boot into nixos in 6s...
+ test -e /dev/kmsg
+ exec

The screen goes black, the minipc is still powered on but nothing happens.

I have to manually power off and power on again.

I get exactly the same behaviour if I just run:

curl -L https://github.com/nix-community/nixos-images/releases/download/nixos-unstable/nixos-kexec-installer-noninteractive-x86_64-linux.tar.gz | tar -xzf- -C /root
/root/kexec/run

If I run dmesg during the 6 sec I get:

[   75.819535] + cleanup
[   75.819573] + rm -rf /root/kexec/kexec/tmp.i3NzDovf9i
[   75.819591] + nohup sh -c 'sleep 6 && '\''/root/kexec/kexec/kexec'\'' -e'
[   75.825248] shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory

Any suggestions?

Thanks

Answer 1 · 2024-03-17T09:20:28.000Z

What was your original kernel version and did it help to drop --kexec-syscall-auto to fix the issue?

Answer 2 · 2024-03-17T09:21:36.000Z

https://github.com/nix-community/nixos-images/blob/6286096fcbda0a30d8698bd2c37e8f595298b3fc/nix/kexec-installer/kexec-run.sh#L65 might have not had this feature yet on 22.11.

Answer 3 · 2024-03-17T14:17:52.000Z

What was your original kernel version and did it help to drop --kexec-syscall-auto to fix the issue?

I was using Fedora 39 with kernel 6.7.6

Answer 4 · 2024-03-17T14:24:48.000Z

This syscall flag is a bit of a hit and miss. Sometimes its needed to fix kexec and sometimes it's not. It's just often hard to re-produce or debug these type of issues, if you have not full control over the hypervisor or if you don't own the hardware.

Answer 5 · 2024-03-17T14:26:17.000Z

In this case fedora was installed bare-metal on a mini pc (Intel N5100), no virtualization.

Answer 6 · 2024-03-17T14:36:45.000Z

I believe there is something related to the hardware.
As starting from the same software base (Fedora 39, 6.7.9, bare-metal), it works without any problem on an old laptop with Intel i6500U.

Answer 7 · 2024-03-17T15:13:48.000Z

How much RAM do you have on this board?

Answer 8 · 2024-03-17T15:14:28.000Z

8 GB, the laptop 16 GB

Answer 9 · 2024-03-17T15:17:39.000Z

Ok. This is more than enough.

Answer 10 · 2024-03-17T15:18:57.000Z

Do get more console output, it may be helpful to comment out these console lines: https://github.com/nix-community/nixos-images/blob/6286096fcbda0a30d8698bd2c37e8f595298b3fc/nix/installer.nix#L12
Unless you are using serial to get the output.

Answer 11 · 2024-03-17T15:22:37.000Z

No, I am not using serial.
Are you suggesting to comment line 12-16?

Answer 12 · 2024-03-17T15:42:23.000Z

Yes. You can rebuild the kexec image and than pass it to nixos-anywhere via the --kexec parameter.

Answer 13 · 2024-03-17T15:46:57.000Z

Thanks for the suggestion, I will give a try in the next days.

Answer 14 · 2024-03-19T08:20:17.000Z

Hi,
as you suggested:

I forked the nixos-images repository and comment the boot.kernelParams section (nix-community/nixos-images@main...yellowhat:nixos-images:main).

Run nixos-anywhere using custom kexec:

ARCH=$(nix eval --raw --impure --expr builtins.currentSystem)

out=$(nix build \
    --option accept-flake-config true \
    --print-out-paths \
    "github:yellowhat/nixos-images#packages.${ARCH}.kexec-installer-nixos-unstable-noninteractive"
)
kexec="${out}/nixos-kexec-installer-noninteractive-${ARCH}.tar.gz"

nix run github:nix-community/nixos-anywhere -- \
    --flake .#htpc \
    --kexec "$kexec" \
    --print-build-logs \
    --debug \
    user@ip

But I get the same behavior, on kexec the screen becomes black with no output.

Answer 15 · 2024-06-30T13:30:41.000Z

You figured anything out here? I've tried two computers (Lenovo m92p and Lenovo T520) and I see the same issue on both of them

You mention 22.11 is working, but can this be done adjusting the flake?, like

  inputs.nixpkgs.url = "github:nixos/nixpkgs/nixos-22.11";

I tried this, but still the same

Answer 16 · 2024-06-30T14:25:46.000Z

This issue has been mentioned on NixOS Discourse. There might be relevant details there:

https://discourse.nixos.org/t/is-nixos-anywhere-supposed-to-work-at-all/48172/1

Answer 17 · 2024-06-30T16:37:47.000Z

There is no also --kexec-extra-flags flag that allows to pass down kexec flags. Interesting ones to try is the --kexec-syscall flag as described here: https://www.man7.org/linux/man-pages/man8/kexec.8.html
Otherwise if you are dealing with local hardware anyway, it might be easier to boot our installer iso that you see here: https://github.com/nix-community/nixos-images?tab=readme-ov-file#iso-installer-images and use nixos-anywhere just to connect against this ip address. If nixos-anywhere detects an installer it won't run kexec.

I tried this, but still the same

In my case, I forked the repo and changed the kexec_url and then run:

nix run github:yellowhat/nixos-anywhere -- \
    ...<opts>

@yellowhat ok, wow; that worked perfectly;). Thanks a bunch

Answer 20 · 2024-07-02T07:34:17.000Z

What kernel version does 22.11 use? Maybe we should provide different kernel versions, but I don't see the pattern yet.

@yellowhat ok, now I'm on another computer, a Microsoft Surface 2 Pro and I get the same error, again;)

I'm confused. I don't understand this bug.

Can you connect to the machine though? It could be also that the tty is connected to an internal serial port.

Also surface pro may not work with the stock kernel: https://github.com/NixOS/nixos-hardware/blob/master/microsoft/surface/common/kernel/default.nix
Best to avoid when you want to primary run NixOS on it.

Answer 24 · 2024-07-06T07:04:48.000Z

I am closing this issue. I don't have the resource and hardware to fix kexec on random hardware. If it happens on some hardware/infrastructure where I have enough access to, I could check it out but otherwise there is nothing I can productivly do.

Answer 25 · 2024-07-06T20:10:27.000Z

I understand that, but I have trouble to understand what the actual problem is. I mean, would it help to use your iso, which you pointed me to or is that irrelevant?

Answer 26 · 2024-07-07T09:08:27.000Z

@madorian Yes. if you boot from the iso, you can avoid using kexec all-together.

Answer 27 · 2024-07-07T23:48:04.000Z

@madorian Yes. if you boot from the iso, you can avoid using kexec all-together.

Not sure I understand this, but anyhoo; are there some instructions on how to generate this iso?

Answer 28 · 2024-07-08T07:11:55.000Z

The regular NixOS install iso from https://nixos.org/download/#

I use the minimal iso.

See the manual:

Answer 29 · 2024-07-08T07:52:22.000Z

I was talking about this iso: https://github.com/nix-community/nixos-images?tab=readme-ov-file#iso-installer-images
it's optimized for nixos-anywhere. You can download it from here: https://github.com/nix-community/nixos-images/releases/tag/nixos-unstable

Answer 30 · 2024-07-08T21:29:18.000Z

I must state that I'm utterly confused;) What are these images and which one to pick?

These images avoid using kexec? I don't understand this part, cause if I boot from your iso, it would be just the same as booting from my iso. I would still have to kexec nixos-anywhere along with disko information, not?;)

Answer 31 · 2024-08-16T19:39:03.000Z

Not all hardware will work with kexec. It's more likely that the iso image will boot correctly though. And if nixos-anywhere detects an installer it doesn't do kexec. See also here: https://nix-community.github.io/nixos-anywhere/howtos/no-os.html
