Description Richard Fan 2024-03-29 02:42:55 UTC

##Description

The issue can be seen if we add below LIBYUI kernel boot parameters during the installation:

extend=libyui-rest-api
YUI_HTTP_PORT=39101
YUI_HTTP_REMOTE=1
YUI_REUSE_PORT=1


And the full boot parameter line is "initrd=initrd splash=silent textmode=1   Y2DEBUG=1 vga=791 video=1024x768 plymouth.ignore-serial-consoles console=ttyS0 console=tty linuxrc.log=/dev/ttyS0 linuxrc.core=/dev/ttyS0 linuxrc.debug=4,trace extend=libyui-rest-api YUI_HTTP_PORT=39110 YUI_HTTP_REMOTE=1 YUI_REUSE_PORT=1 reboot_timeout=0    self_update=0 kernel.softlockup_panic=1  regurl=https://scc.suse.com"


Installation get stuck if I set the ram size to 1gb or 2gb, and I can get some trace log from serial terminal as well.

-----------------------------------------

The issue is not seen with previous build 136.1 [ramsize=1gb] and starts to show up at build 137.1.

Please see openQA job history https://openqa.suse.de/tests/13708336#next_previous


--------------------------------------------

With 1gb memory, I can get the serial log1 [please see attached log1], with openqQA job link https://openqa.suse.de/tests/13845781#step/setup_libyui/4.

With 2gb memory, I can get the serial log2 [Please see attached log2] with openQA job link http://openqa.suse.de/tests/13906674#step/setup_libyui/4

The issue is gone if I set memory size to 4gb, please see openQA job http://openqa.suse.de/tests/13906683#details

Can you please double check if it is a kernel bug or something release to yast install modules?

Do let me know if you need to access my setup to debug.

## Test suite description
Testsuite maintained at https://gitlab.suse.de/qa-maintenance/qam-openqa-yml. Maintainer: QE Core

Installation in textmode and selecting the textmode "desktop" during installation.


## Reproducible

Fails since (at least) Build [137.7](https://openqa.suse.de/tests/13813186)


## Expected result

Last good: [136.1](https://openqa.suse.de/tests/13708336) (or more recent)

Comment 4 Richard Fan 2024-03-29 07:45:08 UTC

I'd like to add more information here:

1. The issue seems happen on x86_64 platform only\
2. The issue can only be seen with TEXTMODE installation, that means we add "textmode=1" and "libyui" parameters to boot parameter at the same time. 

In summary, the below boot parameters can cause the problem.

```
textmode=1
extend=libyui-rest-api
YUI_HTTP_PORT=39101
YUI_HTTP_REMOTE=1
YUI_REUSE_PORT=1
```

To clarify the issue, it is not seen with either 'textmode=1' or libyui related parameters defined.

That means the issue can only be seen with all of these boot parameters added at the same time:

'textmode=1'

AND 

'extend=libyui-rest-api
YUI_HTTP_PORT=39101
YUI_HTTP_REMOTE=1
YUI_REUSE_PORT=1'

Comment 6 Richard Fan 2024-04-02 06:34:39 UTC

Let me add my test results:

1. The issue is not seen with only 'textmode=1' defined 

https://openqa.suse.de/tests/13906657#step/welcome/1 [please ignore the failed test module, it is not related to this bug]


2. The issue is not see with only libyui related parameters defined
