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 1 device (Rpi3+) and 2 environments (cards). armhfCard arm64Card 4.19.0-5 Success Success 5.2.0-2 Failure Failure New firmware for armhfCard 2018-08-05 -> 2019-08-17 // It did not help.

"Hangs" below means that you cannot do anything more with your mouse or keyboard. You have to switch off and on the electricity. Reproducible errors: ReprodError1 week35: // armhfCard // Intermittent error week36 a. Start the computer and wait for the SDDM display manager b. Give Ctrl + Alt + F2 and wait approximately 5 seconds c. It writes below the login row: "bcm2835-power bcm2835-power: Failed to disable ASB master for v3d" // Hangs.

Start the computer and wait for the SDDM display manager b. Wait for the cursor to blink in the input field 40-45 seconds. // Hangs Intermittent errors: IntermError1: // arm64Card and armhfCard a.

IntermError3: // armhfCard. a. Start Kde b. Start Konsole and # tail -f /var/log/syslog // No additonal (error) rows after the computer was hanged c. Start browser Falkon // Hangs. The Falkon window, the mouse cursor and everything else, were visible. IntermError4: // armhfCard. a. Start the computer and wait for the SDDM display manager b. Give password and enter // Hangs IntermError5: // ar64fCard. a. Start Kde b. Start browser Falkon c. Give url address and choose arrow down to the right in the window. // Hangs. Graphic in kernel 4.19.0-5 works without any problem (maybe locks few times per month and a break of electricity is needed). Graphic in kernel 5.2 with its device_tree, locks few times per hour and a break of electricity is needed. I have a feeling that the culprit is the error message "bcm2835-power bcm2835-power: Failed to disable ASB master for v3d" which I got for "ReprodError1" for armhfCard. This configuration works (device_tree from kernel 4.19), but then "bcm2835-power" is not used: # cat config.txt device_tree=bcm2837-rpi-3-b-plus.dtb.4.19 kernel=vmlinuz-5.2.0-2-armmp initramfs initrd.img-5.2.0-2-armmp followkernel Best Regards, Evald
