May 4, 20242 yr I have a Helios64 that I recently reinstalled/updated to the latest Armbain Jammy image after not updating for quite some time and finding some of the repos to be dead. Without the drives initialized the system seems like it will run for days, but with the drives initialized (ZFS), I will get the below error after a few hours of uptime (~8-10 hours). I have seen some threads saying to set the CPU clock to one speed to fix the issue and some people installing a newer kernel (via beta.armbian.com). If anyone has any thoughts on how I could try and make this more stable I would appreciate it.

May 4, 20242 yr Author Thanks. I will look through that. For now I have updated from the beta channel to the latest version 24.5.0 with kernel 6.6.30 and hope that helps in some way.
