Fresh Red Hat 9 installs : LUKS passphrase stops working after 2/3 days

Hi everyone,

Very recently, 2 fresh Red Hat 9 installs got a similar issue about the LUKS passphrase : it stopped working after 2/3 days, meaning a reinstall had to be done.

To avoid any doubt, the passphrase is correct (as it initially works fine) and the proper keyboard is displayed on the LUKS passphrase input screen.

Did anyone encounter such issue or could suggest a solution please ?

Many thanks.
