Hi everybody, I am using Librem 5 for a long time. Since the beginning I experienced unexpected freezes and hard reboots when the phone was tasked with something hard (like accidentally opening unusable Firefox while doing something else). I initially attributed it to low amount of RAM and out-of-m…

I really wouldn’t put swap on a SD card, it’s slow and sounds like asking for troubles. [image] Privacy2: However, I will note that on most systems the default ZRAM is 1/2 the actual RAM total rather than 2 times the RAM total. The current default on Librem 5 is to use 2 times the RAM total.…

[image] Vuntun: ... again inside this cgroup. I also temporarily disabled swap on the MicroSD. This time it was somewhat long, but if finally completed without hard resets. Have you looked at the log files when there are hard resets? When you “temporarily disabled swap on the microSD”, d…

1. Logs I have looked logs. Here are my findings: A lot of redpine_91x errors throughout the logs. There are 5663 such errors in 6 and a half hours (approx. 14.5 such errors per minute). 20:30:37 pureos kernel: redpine_91x: Packet Dropped as Key ID not matched with both current and previous Key…

[image] Vuntun: No, I did not touch ZRAM. It was not disabled and I did not change its configuration. It looks like you’ve got 6GB of ZRAM. That’s probably (assuming you have a non-Liberty version) about 2 times actual RAM. If the stuff in RAM is not very compressible that can result in ove…

[image] dos: The current default on Librem 5 is to use 2 times the RAM total. Filling the RAM up will trigger OOM killer rather than hard resets. I’ve had very bad luck with the OOM killer. I’ve had it take out crucial systems even when there was plenty (e.g 25GB left) of swap left. And one…

[image] Privacy2: Are you sure you didn’t temporarily disable the ZRAM? Yes, I checked logs, the ZRAM was not disabled. [image] Privacy2: you didn’t encounter kernel panics in your most recent freezes Yes, at least they were not recorded into logs. There is a possibility that there wa…

Returning here after almost a month with an update. Disabling my custom-configured swap on a MicroSD indeed significantly reduced frequency of unexpected resets, but did not rule them out completely. They still happen from time to time when connected to a display with a hub. At least now it is not …
