  1. I've had a 100% stable system for 16 days now, no cpufreq tweaks, only vanilla armbian config (+zram though). 17:32:07 up 16 days, 20:13, 1 user, load average: 0,12, 0,17, 0,14 Using this kernel: 5.10.21-rockchip64 And I've _never_ gotten the red led blink when my system froze. Have you tried different or fewer drives?
  2. I've tried to provoke a system freeze with high cpu and IO, but it seems stable for now. 20:05:49 up 4 days, 23:47, 1 user, load average: 0,14, 0,15, 0,11 I'll update this thread if the issue reoccurs.
  3. Just an update from yesterday, no freezes or crashes yet, even though quite heavy IO and CPU.
  4. I did a dist-upgrade yesterday, and I've had two freezes since then due to high IO (probably). But I've reverted the cpufreq tweaks now (ondemand+min/max 400000/1800000), and I never enabled he vdd tweaks in boot.cmd, so there wasn't anything to revert. So we'll see how it goes, I'll try to put a lot of IO load on it the coming days. 5.10.21-rockchip64 #21.02.3 SMP PREEMPT Mon Mar 8 01:05:08 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux
  5. Are you getting data corruption due to the freezes, I mean broken raids or checksum errors if it's zfs? I can provoke a freeze by loading with a lot of IO+CPU at will, so I think the dev's have a real challenge ahead both separating the issues and troubleshooting them. I've lowered the cpufreq min/max to 800mhz now, and max download speed to 7MB/s, hoping that will perhaps help.
  6. I seem to have freezes as well. I stayed on the recommended release with zero updates from the default installation. I'm running Sonarr, Radarr, Jackett, Transmission, Samba, NFS server and Zram swap. Linux muzzy 5.8.14-rockchip64 #20.08.10 SMP PREEMPT Tue Oct 13 16:58:01 CEST 2020 aarch64 aarch64 aarch64 GNU/Linux I've also changed the cpufreq config to avoid issues. Locked at 1,2ghz min/max, performance govenor. It seems like when I do a lot of I/O and put a high load on the cpu, the system just freezes. There's nothing in the syslog but I haven't looked in the serial console. I'm only running SSD's in this machine, so there's no shortage of bandwidth on the drives. If there's no load, I haven't had one freeze at all. Medium load doesn't seem to be an issue either. Has anyone tried adding active cooling on the cpu? I'm guessing this is the same issue that was posted about on the 27th of October in the blog, why hasn't there been an update on it? And for the mods: how can I remove this forum posting limitation, like one post per week or something?
  7. What was your speed when the disks were mounted in a different machine? 7,2rpm sata drives usually sustain these kind of numbers for sequential reads and writes, more speed can be attained by adding more spindles (drives). Although I think your read speed potential should be a bit higher. Try piping a file to /dev/null to measure the real read speed of one disk first and piping /dev/zero (make it larger than the cache) to a file on that disk or another disk to get the max write speed. There's some more benchmarking options listed in this post on ubuntuforums: https://askubuntu.com/a/991311 Br Seneca
