As you can see, my load averages are in the millions...

Hi, thanks reporting this.

Here is:
$ inxi -Sxx
System:    Host: mageia.local Kernel: 5.10.48-desktop-1.mga8 x86_64 bits: 64 compiler: gcc v: 10.3.0 
           Desktop: KDE Plasma 5.20.4 tk: Qt 5.15.2 wm: kwin_x11 dm: SDDM Distro: Mageia 8 mga8

$ top
> top - 22:55:30 up  1:20,  2 users,  load average: 0,80, 0,74, 0,74

OK. No such strange numbers...
I don't really know why you get such numbers, as you reported that compiling this utility from sources, it is same.

@Stig, you did mention on upstream report that you use Cauldron with a 5.10.46 Kernel... This is a Mageia 8 Kernel. I'am not affected, nor upstream dev.

Can you confirm which kernel version you use?

Comment 4 Stig-Ørjan Smelror 2021-07-13 23:11:35 CEST
Yes, I'm using a custom kernel because the Cauldron kernel has issues that I haven't reported yet.

Cheers,
Stig

@Stig : thank you for the screenshot, & upstream ref.

Following Stig's upstream bug report (comment 2, worth reading)), I think this bug is now invalid.

On my M8 system with kernel 5.10.46-desktop-1.mga8:
 top - 20:49:57 up 23 min,  1 user,  load average: 0.13, 0.28, 0.34
 $ cat /proc/loadavg
 0.64 0.40 0.38 3/471 9372

If others agree, let's close this.
