suspend-related issues on kevin?

[sarnold]

Howdy, I actually have a different build setup (forked and hacked a long time ago: https://github.com/sarnold/chromebooks) with a different focus, and I can't really say I'm reporting anything, so I'm really just asking: have you run into and/or fixed any "freezing" issues on kevin or other gru-based chromebooks? I've only really seen this on recent 6.x kernels with ubuntu and I don't really have anything diagnosed. So far I've been trying to rule out things like systemd/logind suspend and DPMS powersave, etc.

Thanks in advance either way; hopefully I'll have a chance to check out your image builds after I clear out some "free" time.

i'm not aware of any freezing issues with gru, but i'm not using them often, so i cannot say for sure that there really aren't any ...

@sarnold - Do you have other units to attempt to reproduce the issue on? I ask since I had a single unit, from a previous batch of eduGear M4 units, that would just freeze at random times. I tested on more than five other units and could not reproduce. Hence I decided the issue was on only the single unit. I figured it was something damaged somewhere that I could not find and moved on.

I have a few other armv7 chromebooks but only 1 of each type. I pretty much narrowed it down to ubuntu 20.04 (so far) since it doesn't happen with bookworm/gnome at all, nor does it happen on veyron-minnie with focal either, so there ya go. Thanks for the feedback!
