We need more information here ;-). Can you please provide a full boot
log from a good kernel, then boot into the broken until triggering the
issue the first time, then provide please as well the boot log from
this.

Can you additionally test as well a kernel from unstable (6.12.33-1)
and experimental (6.15.4-1~exp1) to verify you can trigger the issue
there as well (or not)?

Regards,
Salvatore
