   Dear Maintainer,   
      
      * What led up to the situation?   
   When I upgrade the news kernel package in sid,  my notebook's lightdm can't   
   start. From /var/log/Xorg.0.log, it's said:

   I find kernel load i915 driver module almost has two seconds delay,   
   it's too slow.   
      
   When X.org start, the i915 driver still not load, so X.org can't find   
   /dev/dri/card0.   
      
   When using stable kernel 6.1.0-41-amd64, this bug is not exist,   
   i915 module load normal.   
      
      * What outcome did you expect instead?   
   I hope kernel can load i915 module normally.
