Freesh Linux 6.17 cannot see all the ram available on my 32 bit cpu

[charles.murdock]

Hi
I have GNU/Linux Debian Trixie 32 bit, and the Freesh kernel 
6.17.0-gnu-1.0 does not see all the available ram.
There are 2Gi on my pc and kernel 6.17 can see only 854Mi like the first 
Linux 6.16 version.

lscpu return:
