Orange Pi 5+ heatsink/fan report:

Results in it's own kernel build (6.9-rc1 with rk3588 collabora patches) in 116m56s with 0 throttling, finally!

Comparing the kernel build time to:

  • household's gaming desktop (AMD Ryzen 7 5800X3D): 26min
  • hetzner CAX21: 55min
  • laptop with Intel i5-1240P: 1h11min
  • same orangepi5+ with a bad heatsink (from the same purchase of acrylic case; it slightly throttled): 2h31min
  • Intel Celeron J4115: 4h40min

Finally it's robust enough so I can move things from my Celeron home server now. I appreciate everyone's tips here over the last 6 months. :D

@motiejus:jakstys.ltmotiejus looking at it now, looks like it always runs at 1800MHz/2400MHz. And there is no output from dmesg | grep cpufreq. How is it supposed to look like? 11:08:16
@motiejus:jakstys.ltmotiejus * looking at it now, looks like it always runs at 1800MHz/2400MHz, which is not desirable for power draw, I guess. And there is no output from dmesg | grep cpufreq. How is it supposed to look like? 11:08:36

11:09:29
@k900:0upti.meK900Like two weeks?11:09:36
@motiejus:jakstys.ltmotiejus2w seems still reasonable (I usually wait between 10 to 20 days, very rarely more or less than that)11:10:36
@motiejus:jakstys.ltmotiejusthough I do understand target country may matter quite a bit11:10:53
@motiejus:jakstys.ltmotiejusdid you order the big fat piece of copper you mentioned previously?11:11:16
@k900:0upti.meK900 Two weeks since last update 11:13:02
@k900:0upti.meK900More specifically11:13:06
@motiejus:jakstys.ltmotiejus answering my question about cpufreq: I guess it's not supposed to work now, but soon (and here] 11:34:08

mmcli (modem manager) is the first thing to check, if you're looking to debug

15:46:13
@colin:uninsane.orgColin

mmcli --list-modems will check if it even sees the modem

15:46:38
@wonder-tmp:the-apothecary.clubIris [you&] ∈ Wonder& [y&]

No modems were found

15:46:57
@colin:uninsane.orgColinmmcli --set-logging=DEBUG might tell you why it fails to find anything 🙃️15:47:13
@wonder-tmp:the-apothecary.clubIris [you&] ∈ Wonder& [y&]what does it do? on its own it's just set a logging level15:48:30
@colin:uninsane.orgColin

oh, sorry. you would want to pair that with journalctl -u ModemManager

@wonder-tmp:the-apothecary.clubIris [you&] ∈ Wonder& [y&] sim-missing is bad, there most certainly is a sim in the slot 15:56:54

In reply to @wonder-tmp:the-apothecary.club
sim-missing is bad, there most certainly is a sim in the slot

when i was in this situation on a pinephone (sim-missing despite a sim card definitely being there), it turned out i had to do some special stuff to properly initialize the modem before ModemManager could talk to it. eg25-manager does that for the pinephone, if it's a different phone i wouldn't have a clue.

16:26:44
@wonder-tmp:the-apothecary.clubIris [you&] ∈ Wonder& [y&]this is a pinephone16:36:07
@wonder-tmp:the-apothecary.clubIris [you&] ∈ Wonder& [y&]i'm not entirely sure what's going on in the linked issue but it looks like they resolved some build issue16:36:49
