A significant update.
After considering these in /var/log/error.log :
Jan 1 10:00:04 asus0 kernel: [ 2095.395568] xhci_hcd 0000:03:00.4: PCI post-
resume error -19!

cleaning up
a web search led me to unload xhci_* on suspend, and load them again on
resume. I went through a bash script in /usr/lib/systemd/system-sleep/.
At least 25 suspend/resume cycles in a row have succeeded. I tested both
s2idle and deep by tweaking SuspendState={freeze,mem} in sleep.conf.
Using linux-6.1.3, that misbehaves similarly to 6.1.2 and 6.1.1.
The drawback is that all USB connections get lost. Also, opening the lid does
not trigger anything when using s2idle, while closing the lid does trigger
suspend in both modes. I'll do with these.
I'll know in the coming days if delayed cycles are well managed.
Regards.
