 6.12.38-1 is not the most current kernel available in trixie, pliease 
 do update to 6.12.48-1 and let us please know if the problem persist. 
  
 If yes, then we would need (ideally a full) boot log, but if nothing 
 get recorded in logs, then the netconsole[1] approach might help

 On UEFI system pstore alterantively might help us as well. 
  
 But first upgrade your kernel to the most current one in trixie, to 
 determine if the problem persists.
