Please go to  rockbox / debug / dump ata identify info, and send me the /identify_info.bin that is created.

I suspect what's going on is that the CF card you're using doesn't properly implement power saving functions, so the shutdown is hanging while waiting for the CF card to acknowledge a clean shutdown.

Sent message with the dump you requested me.
If could help, these days i'm disabling backlight before shutting down ipod, to prevent battery drain.
Only yesterday evening i tried, after update, to leave backlight on, without resolving issue.

PeppeNT:
Solved. I made it faster to do myself before waiting your support. I edited source code and added function backlight_set_timeout(-1); before lcd shutdown in powermgmt.c and compiled. This solved my issue.
Please when an user asked help, and you do not want to help him, say it, because, even if this is an open source project and nobody must do nothing, is appreciated to say if you do not have much time to help, so users do not have to wait infinitely an help that won't arrive.
Thanks much.

PS. it wasn't a power saving feature

The backlight does not block shutdown.  In other words, the player is still _on_, and still draining the battery, only more slowly.

An apparently-identical issue arose with an older ipod version due to ATA powermgmt code that the iflash adapters bypass.  The ipod6g+ series use a different ATA driver that currently has no awareness of the iflash adapters and the need to disable power management on those things.

So it's a good thing you managed to support yourself, eh?

Please try this and see if it shuts down cleanly.

Oh, one more thing that occurred to me.  Can you also send me the .rockbox/config.cfg too?
