I initially started getting this issue on daedalus and had no idea what caused it.
Made a fresh install of 17.10 now, but kept my home partition and the issue persisted.
It does not happen on a live Netrunner. And may not happen on a completely fresh install, but I have no aditional storage to back up my home partition and resetting everything would be a very huge pain.
Everything seems to be working without issue despite the message.
Can you check your temperature on the system.
You can do so by running sensors from the lm-sensors package in a terminal.
I fear it might be overheating.
The message appears every time I go into suspension and wake my laptop up again.
Even if it is just a few seconds long.
I did a check with sensors, before the suspend, around 40°C after some light daily usage.
Then I suspended it for about an hour, after that the cpu was 25°C.
Did also some stress testing in windows to see if it is a hardware temperature issue, and at 100% load on all 4 cores, with Turbo Boots to 3.2 GHz, it reached a max temp of 90°C, which is hot, but not critical, since in actual use-cases it never gets to that amount of load.
Should I do some stress tests under linux as well? Or is there a way to constantly monitor the temp over a long time?
Ah ok 90 is very high. I think the computer should turn off at 93 or 95.
Though if the issue only appears on standby it is more likely related to a broken acpi integration of your Mainboard. Try searching and installing UEFI/BIOS Updates and see if it fixes stuff.
90 is fine for an old dusty laptop on maximum overclocked cpu workload
It took me a while to get back to this issue, I recently reinstalled all my os on the laptop.
Before I was in legacy(bios) mode, because I used another os, that didn’t support uefi.
I did a complete clean netrunner install now in uefi and in the process updated my uefi/bios to the newest version that is available from the manufacturer. (I have an Acer Aspire V3 772g)
The error message is still there, every time after I wake netrunner up from suspention.
(But as I said, it was never an issue in the first few months of running Netrunner Daedalus. It seems like either something changed in the os, or something broke in my system hardware, during that time.)
