We’re currently suffering from a similar situation.
Debian buster/arm64 installation, straight from this script:
https://evolvis.org/plugins/scmgit/cgi-bin/gitweb.cgi?p=shellsnippets/shellsnippets.git;a=blob;f=posix/mkrpi3b%2Bimg.sh;hb=HEAD
With the buster kernel, the analog audio doesn’t work, and
3D graphics using llvmpipe are really slow, but the system
is, overall, stable.
With the backports kernel and either buster’s raspi3-firmware
or sid’s raspi-firmware (tested both), 3D graphics are accelerated,
poweroff/reboot don’t work, and the system crashes after some
uptime (confirmed it’s not a thermal issue, and the official
PSU is used, so power is enough).
With the sid kernel and sid’s raspi-firmware, the same issue
happens. We managed to get a serial console running, and the
crash message is what led us to this bugreport:
[timestamp] bcm2835-power bcm2835-power: Failed to disable ASB master for v3d
This is a fairly stock setup, with CMA raised to 128M and
consoles fixed (see the outstanding bugreports in the
raspi3-firmware/raspi-firmware package), and video size fixed:
tglase@tglase:/mnt $ grep '^[^#]' etc/default/raspi-firmware
CMA=128M
CONSOLES='ttyS1,115200 tty0'
tglase@tglase:/mnt $ cat etc/default/raspi-firmware-custom
disable_overscan=1
Incidentally, shortly before, we see this in syslog:
Jan 1 01:00:26 rpi3bplus kernel: [ 26.255342] broken atomic modeset userspace detected, disabling atomic
Unsure whether it’s related.
Other things are reports in Fedora with instabilities relating
to the RPi 3B+ and power management…
Please advice as to a fix ☻
