The logs attached to the original bug relate to the issue I care about.
The logs attached to fulfill ubuntu-kernel-bot demands contain the dmesg
output produced when doing `modprobe -r -v i2c_bcm2835` that demonstrate
how these kernel messages share some similarities.
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Description changed:
Since upgrading to 5.4.0-56-generic my RPI3 devices started freezing
randomly, about once every few hours.
-56, -58 and -59 are affected, reverting *only* the kernel back to -53
got me 3 days without freeze. 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

Title:
5.4.0-58-generic: Raspberry Pi 3 arm64 occasionally unresponsive
Status in linux package in Ubuntu:
Confirmed
Bug description:
Since upgrading to 5.4.0-56-generic my RPI3 devices started freezing
randomly, about once every few hours.
-56, -58 and -59 are affected, reverting *only* the kernel back to -53
got me 3 days without freeze. 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):

13:52:01.839310 kernel: raspberrypi-clk raspberrypi-clk: Failed to change
