   Quick addendum:   
      
   I had not tried Debian 12, because CONFIG_RPCSEC_GSS_KRB5_ENCTYPES_AES_SHA2   
   was not enabled in the shipped Kconfig.   
      
   I just spun up a Debian 12 VM and installed the aforementioned   
   upstream 6.17.8 with Fedora 43 Kconfig kernel and confirmed the issue   
   also occurs on Debian 12.
