The system may still be running as a sound is emitted when the power button is pressed (only way to escape from the system hang).

Not my area of expertise, but nevertheless pretty sure this is the same
issue already discussed here, as it's a GT218 there as well at 6.4.7 is
the version that commit was backported to:

https://lore.kernel.org/all/20230806213107.GFZNARG6moWpFuSJ9W@fat_crate.local/

No final solution ready yet, but looks like the culprit will be reverted.
