Package: linux-image-armmp
Version: 5.2.0-2

Hello,

I have made a guide for Debian on Rpi here:
https://github.com/evasjo/DebianSbcRaspberry

I have 3 devices (Rpi) and 2 environments (cards).

        armhfCard	arm64Card
4.19.0-5:
Rpi2b   Success     NotPossible32bitCpu
Rpi3b   Success     Success
Rpi3b+  Success     Success
5.2.0-2:
Rpi2b   Failure     NotPossible32bitCpu
Rpi3b   Failure     Failure
Rpi3b+  Success     Success

The display manager SDDM does not start with kernel 5.2" for combinations above.

New firmware for armhfCard	2018-08-05 -> 2019-08-17	// It did not help.
New firmware for arm64Card	2018-12-25 -> 2019-08-17	// It did not help.

# lsmod|grep -i vc4		// There are rows i.e. the module is loaded
# journalctl|grep -i bcm
bcm2835-power bcm2835-power: Timeout waiting for grafx power OK	// A
lot of these rows

"Success", 4.19.0-5:
Kde is running.
shutdown -h now	// It does disconnect the power to the monitor.
shutdown -r now	// It restarts the computer.

"Success", 5.2.0-2 (5.2.9.1):
Kde is running.
shutdown -h now	// It does not disconnect the power to the monitor. It
leaves the monitor on with the text (last row): "reboot: System
halted"
shutdown -r now	// It does not restart. It leaves the monitor on with
the text (last row): "Reboot failed -- System halted"

The "Failure" culprit seems to be "bcm2835-power" for Rpi2b and Rpi3b.

Best Regards,
Evald

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
