[SOLVED] 9.3.2: dmesg full with "mempolicy: Request to set policy to 3 ignored" messages

[dheijl]

Since installing Moode 9.3.2 the dmesg log is continually spammed with these messages: 
```

I know it's not a Moode problem, it's a Raspbian problem with kernel 6.12, see for instance this conversation: https://forums.raspberrypi.com/viewtopic.php?t=386126.

I'm just signaling it, and I suppose we will have to live with it until it's solved in Raspbian.

libnuma1 was the issue.
I fixed it on my moOde instance by doing: sudo apt install libnuma1
This installed a newer version of the lib where the issue is fixed.

Here's the version that ships with r932

Code:

pi@moode9:~ $ dpkg -l | grep libnuma1

ii  libnuma1:arm64                       2.0.18-1~rpt1                          arm64        Libraries for controlling NUMA policy

[ils1974]

2.0.18-1 is indeed the version that works. However, if you do an inplace update, this one wasn't upgraded I believe, and this is when you've the issue.

[Tim Curtis]

Correct. The in-place update only does the kernel and the list of moode packages below.

Code:

# Part 2: List of package updates (cumulative)
PKG_UPDATES=(
moode-player=9.3.3-1moode1
alsa-cdsp=1.2.0-2moode1

python3-camilladsp=3.0.0-1moode1

libupnpp16=0.26.7-1moode1
pleezer=0.16.0-1moode1
upmpdcli=1.9.0-1moode1
upmpdcli-qobuz=1.9.0-1moode1
upmpdcli-tidal=1.9.0-1moode1
)

There used to be some additional firmware- packages but those were removed to avoid any of them possibly failing and causing the entire update to be cancelled.

Since moode packages are "apt-mark hold" its possible to "apt update && apt -y upgrade" a system and not break anything unless the upgrade contains a new Kernel or version of PHP. A kernel upgrade would cause the aloop and pcm1794a drivers to revert to stock and thus not support 384K rate. A new version of PHP always has its version string as part of its /etc dir and so it causes breakage in moode.

Code:

pi@moode9:~ $ cat /etc/moode-apt-mark.conf

libnuma1 was the issue.
I fixed it on my moOde instance by doing:  sudo apt install libnuma1
This installed a newer version of the lib where the issue is fixed.

I can confirm that

Code:

sudo apt install libnuma1

fixes the issue, thanks!
