At that point it gets stuck, pressing Ctrl-C causes a clean reboot

Thanks for reporting this, but can you please give the background: the Classic ISO, 64-bit, Mageia 8 Alpha, from USB - for example; all guessed.

The cauldron netinstall iso x86_64, as a cdrom in kvm.

Comment 3 Pascal Terjan 2020-06-12 22:12:53 CEST

I confirmed the problem is with the stage 2 by manually selecting mirror after booting on the cauldron image and pointing to http://ftp.free.fr/mirrors/mageia.org/distrib/7, it works well.

Thank you for the extra information, which should help looking at this.

Assigning to the 'tools' team.

Comment 5 Thierry Vignaud 2020-06-15 06:47:17 CEST

This looks to me more like the big systemd update broke rescue when it got rebuilt…

Comment 6 Pascal Terjan 2020-06-15 17:04:04 CEST

One thing I noticed is that mageia-rescue starts with:

systemctl start systemd-udevd
udevadm trigger --type=subsystems --action=add
udevadm trigger --type=devices --action=add

While I would expect systemd-udevd to already be running from the initrd.

I don't know if it could cause a problem but at least it doesn't seem useful anymore

Comment 7 Thierry Vignaud 2020-06-15 18:16:50 CEST

I was wondering if gcc 10 might miscompile rescue bits in mdk-stage1

Comment 8 Pascal Terjan 2020-06-15 18:24:58 CEST

Launching rescue-gui works fine on my machine so I think the problem is in the service (mageia-rescue) but not sure where it gets stuck

Comment 9 Thierry Vignaud 2020-06-16 13:56:01 CEST

Fixed

Resolution: (none) => FIXED
Status: NEW => RESOLVED

Comment 10 Lewis Smith 2020-06-24 20:55:42 CEST

A late addendum (been sitting around), for the record, even though the bug is fixed.
I tried this with the M8 alpha 1 Classic ISO, and the bug was true. I got the output shown in comment 0 on the Ctl/Alt/F1 console; and on the Ctl/Alt/F3 one:
* third party: no modules found
* killed shell
* stage 1: disconnecting life support system
