The README for E14 Gen2 mentions some hibernation problems with Ryzen. I had problens on the E16 Gen2 with Debian 12 stable and AMD Ryzen 7 7735HS with Radeon Graphics" and BIOS R2KET33W (1.16). While standby worked out of the box, hibernation did not. On resume it would show "Resuming from hibernation" for some time and then switch to black screen and become totally unresponsive. I have debugged for some hours and finally it is working!
Findings:
- use a newer kernel than the 6.01 kernels from Debian. I personally recommend the Liquorix kernel (which is at 6.14 currently) (https://liquorix.net/) Nice side effect: it seems to boot much faster that the stock kernel
- have a swap partition or swap file that matches your RAM size (the Liquorix kernel compressed the RAM image in the swap space so probably the size can be lower, too, but I have not investigated into this.
As I have replaced my unreliable RTL wifi card by an Intel one I also had to install a current firmware for that device. For a stock system this should not be necessary but I think it is advisable nevertheless to activate the bookworm-backports repo in apt and install the backported firmware packages from there.
