Diagnostics so far have not turned up anything useful, still busy figuring out cross-compile bisect and a reasonably fast reproduction. The devices are also known as (/proc/device-tree/compatible) raspberrypi,3-model-bbrcm,bcm2837 raspberrypi,3-model-b-plusbrcm,bcm2837 I only use them in ARM64 mode, and I only run -generic kernels via Pete Batards EDKII builds. (unreliable, slow) reproduction: 1. run affected aarch64 kernel 2. set low non-zero /proc/sys/kernel/hung_task_timeout_secs 3. utilize xorg through vc4 kms 4. check dmesg when display freezes symptom 1 (always the same -62): 13:52:01.832230 kernel: raspberrypi-firmware soc:firmware: mbox_send_message returned -62 13:52:01.839310 kernel: raspberrypi-clk raspberrypi-clk: Failed to change pllb frequency: -62 Note: similar message in Bug 1889637 symptom 2 (varying hangs): [Dez15 16:09] INFO: task kworker/2:1:36 blocked for more than 120 seconds.
