Synopsis: Raspberry Pi 3B+ panic on changing video0 permissions for motion
Category: arm
Environment:
System : OpenBSD 6.9
Details : OpenBSD 6.9-beta (GENERIC.MP) #1056: Sat Mar
6 14:04:42 MST 2021
[email protected]:/usr/src/sys/arch/arm64/compile/GENERIC.MP
Architecture: OpenBSD.arm64
Machine : arm64
Description:
panic occurs when _motion has permission to access camera
How-To-Repeat:
attach Logitech webcam, chmod g+rw /dev/video0, reboot
(where _motion is in the group assigned to /dev/video0)
Fix:
unknown. If _motion's group doesn't have access, then
the panic does not occur. I've tried variations on the group,
when camera is plugged in, starting and stopping motion, etc.
I see a similar error from 2017 and am including it at the end of
this email. System always froze when trying
machine ddbcpu x (for x in 0,1,3)
If motion should work with this camera, I can try it
on other Raspberry Pi 3B+ and/or other cameras in the
future.
I'll number and summarize the sections I include.
1. output of sendbug -P.
2. /var/run/dmesg.boot
3. pkg_info (motion and dependencies)
4. permissions
5. motion messages
6. rebooting so camera can be detected.
ddb panic, trace, registers, ps, dmesg
7. similar error, openbsd-bugs, 2017-06-09
----------------------------------------------------------------------
1. output of sendbug -P. It outputs the following at the end:
cp: /var/db/acpi/*: No such file or directory
b64encode: *: No such file or directory
dmesg:

2. /var/run/dmesg.boot
after rebooting. However, after
the panic, the last thing I did from ddb was boot dump,
causes the system to freeze, so the /var/run/dmesg.boot is from the
following successful boot. Probably my fault for not attaching
a separate USB to store the dump.
