rumking Posted August 23, 2023 Share Posted August 23, 2023 I had similar problem (not quite the same from what I remember), but i was receiving kernel panic on armbian 23.5, kernel 6.1.36 and the issue was caused by the start of the armbian-ramlog.service. Once the service was disabled, it booted every time. Disabling the service was discussed here as well: 0 Quote Link to comment Share on other sites More sharing options...
Rmleonard Posted September 5, 2023 Author Share Posted September 5, 2023 this was "sort of" a Solution.... I've tinkered both armbian-ramlog and armbian-zram-config such that they are essentially disabled (but still in the system, in case something I don't know about makes a reference call to them) the edits in the /etc/defaults/ in armbian-ramlog I set ENABLED to false and in armbian-zram-config ENABLED=false SWAP=false everything else is commented out Does this stop the random lockups - no ----- they are MUCH more infrequent and more often than not I can find log files with information --- I've also just gotten the save/boot to/from eMMC to work -- so I'm finally working from "memory" and not from the SD card... I have the board out of the Helios box and I've been running CPU stress tests --- s-tui + stress and it runs and cooks until it doesn't -- when it quits there doesn't seem to be a "panic" or "system dump" -- the error LED doesn't even blink or show --- it just "stops" I'm not convinced that this is the correct spot for this discussion and I'll keep looking for more info... and a better forum to post.... Thank You rumking for the direction you pointed me towards!!! Rich 0 Quote Link to comment Share on other sites More sharing options...
rumking Posted September 9, 2023 Share Posted September 9, 2023 Our use case may be different (I personally dont mind running old buster or bullseye, but I want kernel 6.1 'cause I use btrfs-raid1). It has been discussed, that CPU settings in armbian-config improves stability. I am running: - min CPU speed 408MHz - max CPU speed 1.2GHz - governor set on performance The stability improved RAPIDLY - the system runs several days, I tested btrfs balance/replace - without issues. My system is: - image Armbian_21.08.1_Helios64_bullseye_current_5.10.60.img.xz - newer images occasionally freeze during the boot sequence, I dont mind older system... - apt install linux-image-edge-current - to get kernel 6.1, you could install headers as well for DKMS - I had SERIOUS network issues all the time - I gave up and bought usb to ethernet adapter, after that, no issues with network Hope this helps someone. 0 Quote Link to comment Share on other sites More sharing options...
prahal Posted November 17, 2023 Share Posted November 17, 2023 @RmleonardI have similar crashes but have not found a simple reproducer. When you say you are able to reproduce with the board out, do you mean without anything plugged into it except the power adapter and ethernet? I was testing if it was not related to PCIe/SATA of the board but if you are able to reproduce without any disks plugged into the board that would help me phase out this option. Also, you don't remember if you updated the OS. But do you remember if you ever updated before? And if so when was the last update you remember doing? 0 Quote Link to comment Share on other sites More sharing options...
Rmleonard Posted November 17, 2023 Author Share Posted November 17, 2023 i've taken the whole bloody thing to pieces. i have the motherboard alone on my workbench, i feed it power, ethernet, usb-c for console access.. it boots off of emmc. so, it is EXTREMELY unlikely that there is a ground/short/earthed connection. i use picocomm to sign in to the console to watch the pre-boot. everything else is via ssh 0 Quote Link to comment Share on other sites More sharing options...
Rmleonard Posted November 17, 2023 Author Share Posted November 17, 2023 i created 10 crash files (over time) to see if it always died/crashed at same memory location, answer - no... BUT, of this latest batch of 10 dump files - all were "swapper/4 cpuid 4" which makes me wish i could disable the 2 core sub processor and run the system off the main 4 cores... if i still have crashes, flip the issue, make system run off the 2ndary cpu alone and see how it runs as a thought 0 Quote Link to comment Share on other sites More sharing options...
