Tomte Posted October 22 Share #1 Posted October 22 Hello, I have installed DSM 7.2.2-72806 using ARC on a Futro S920 using a DSM723+ image. Gernerally, it is working fine. However, hibernation (Ruhezustand) of the HDD does not work. I investigated what is happening and found the following message regularly in /var/log/messages: 2024-10-22T07:25:43+02:00 SynoTest kernel: [ 130.859306] synobios get empty ttyS current 2024-10-22T07:26:44+02:00 SynoTest kernel: [ 192.018746] synobios get empty ttyS current 2024-10-22T07:27:45+02:00 SynoTest kernel: [ 252.895842] synobios get empty ttyS current 2024-10-22T07:28:46+02:00 SynoTest kernel: [ 313.770127] synobios get empty ttyS current Same in kern.log. The futro has 3 serial ports, disabling them does not help. I found the issue also in this forum for tinycore redpill, but no solution. Has anyone an idea, what to try next, please?

Tomte Posted October 23 Author Share #2 Posted October 23 Hello, I disabled all serial ports in the BIOS and got rid of this issue after a reinstall. Now I still have: 2024-10-23T20:15:32+02:00 SynoTest kernel: [ 3763.357068] Cannot get i2c adapter 2024-10-23T21:15:33+02:00 SynoTest kernel: [ 7365.187621] Cannot get i2c adapter Has anyone an idea of how to fix this?

Tomte Posted October 24 Author Share #3 Posted October 24 (edited) In the BIOS, I switched all peripherals off, which I am not using, like: - UEFI Network Stack - Sound card - high precision timer - parallel port - all serial ports Hibernation looks good. No log entries now for hours. Edited October 24 by Tomte Quote Link to comment Share on other sites More sharing options...
