Can you check the newest version? We think that https://github.com/RedPill-TTG/redpill-lkm/commit/29637db757d8ad0240e161136db814d5bfd31c33 should fix this problem.

compilation 021ed51 Is there a problem with my write boot method? I use dd if=$(ls -lt /volume1/homes/zh/app/redpill-tool-chain/images/redpill-* | awk 'NR==1{print $9}') of=/dev/synoboot bs=4M;sync to write the command to boot the USB flash disk

Now it's replaced by a large number of newspapers

That is actually normal - it simply logs every ioctl to a drive the DSM makes (and it "pings" all disks every few seconds). We will disable that log by default. As long as the RTC issue is gone it's all good :)

Feel free to reopen the issue if you get the RTC crash again.
