SubjectBug#1127995: linux: Boot hangs at flashing underscore after libvirtd
Message-ID<Movdv-Cnk-1@gated-at.bofh.it>
Source: linux
Version: 6.12.69-1
Severity: important
X-Debbugs-Cc: vivekquissor@gmail.com

Dear Maintainer,

System boots successfully through services but hangs with flashing underscore after last [OK] message of "started libvirtd.service".

No further progress to graphical login

TTY 2-6 accessible

systemctl status sddm shows active (running) initially
journaljtl -u sddm -b only shows:

Initializing
Starting
Logind interface found

Main workaround was booting into older kernel 6.12.63 works perfectly
Forcing DisplayServer=x11 does nothing

Expected: SDDM login screen appearing

Observed: Stuck flashing underscore post-libvirtd, no GUI

Steps to reproduce:
Boot with problematic kernel
Observe boot messages reach libvirtd OK
Flashing underscore present

Hardware -
I5 7500
MSI H110i PRO
GTX 1050 2GB
32GB RAM


Thanks

Can you please provide the full boot log from the system boot  where
you do not get the graphical login. You might be able to access the
log online if the system is accessible via ssh or retrospectively from
the system journal.

Additially please provide the information gathered by 'reportbug
kernel' so we gather inforation on HW, system configuration, loaded
modules.

Regards,
Salvatore
