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 [hidden email]:/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: OpenBSD 6.9-beta (GENERIC.MP) #1056: Sat Mar 6 14:04:42 MST 2021 [hidden email]:/usr/src/sys/arch/arm64/compile/GENERIC.MP real mem = 957190144 (912MB) avail mem = 895352832 (853MB) random: good seed from bootblocks mainbus0 at root: Raspberry Pi 3 Model B Plus Rev 1.3 cpu0 at mainbus0 mpidr 0: ARM Cortex-A53 r0p4 cpu0: 32KB 64b/line 2-way L1 VIPT I-cache, 32KB 64b/line 4-way L1 D-cache cpu0: 512KB 64b/line 16-way L2 cache cpu0: CRC32,ASID16 cpu1 at mainbus0 mpidr 1: ARM Cortex-A53 r0p4 cpu1: 32KB 64b/line 2-way L1 VIPT I-cache, 32KB 64b/line 4-way L1 D-cache cpu1: 512KB 64b/line 16-way L2 cache cpu1: CRC32,ASID16 cpu2 at mainbus0 mpidr 2: ARM Cortex-A53 r0p4 cpu2: 32KB 64b/line 2-way L1 VIPT I-cache, 32KB 64b/line 4-way L1 D-cache cpu2: 512KB 64b/line 16-way L2 cache cpu2: CRC32,ASID16 cpu3 at mainbus0 mpidr 3: ARM Cortex-A53 r0p4 cpu3: 32KB 64b/line 2-way L1 VIPT I-cache, 32KB 64b/line 4-way L1 D-cache cpu3: 512KB 64b/line 16-way L2 cache cpu3: CRC32,ASID16 efi0 at mainbus0: UEFI 2.8 efi0: Das U-Boot rev 0x20210100 apm0 at mainbus0 simplefb0 at mainbus0: 656x416, 32bpp wsdisplay0 at simplefb0 mux 1 wsdisplay0: screen 0-5 added (std, vt100 emulation) "system" at mainbus0 not configured "axi" at mainbus0 not configured simplebus0 at mainbus0: "soc" bcmclock0 at simplebus0 bcmmbox0 at simplebus0 bcmgpio0 at simplebus0 bcmaux0 at simplebus0 bcmdmac0 at simplebus0: DMA0 DMA2 DMA4 DMA5 DMA8 DMA9 DMA10 bcmintc0 at simplebus0 bcmrng0 at simplebus0 pluart0 at simplebus0: console bcmsdhost0 at simplebus0: 250 MHz base clock sdmmc0 at bcmsdhost0: 4-bit, sd high-speed, mmc high-speed, dma dwctwo0 at simplebus0 bcmdog0 at simplebus0 bcmtemp0 at simplebus0 "local_intc" at simplebus0 not configured sdhc0 at simplebus0 sdhc0: SDHC 3.0, 200 MHz base clock sdmmc1 at sdhc0: 4-bit, sd high-speed, mmc high-speed simplebus1 at simplebus0: "firmware" "clocks" at simplebus1 not configured "expgpio" at simplebus1 not configured "power" at simplebus0 not configured "mailbox" at simplebus0 not configured "gpiomem" at simplebus0 not configured "fb" at simplebus0 not configured "vcsm" at simplebus0 not configured "clocks" at mainbus0 not configured "phy" at mainbus0 not configured "arm-pmu" at mainbus0 not configured agtimer0 at mainbus0: 19200 kHz "leds" at mainbus0 not configured "fixedregulator_3v3" at mainbus0 not configured "fixedregulator_5v0" at mainbus0 not configured "bootloader" at mainbus0 not configured usb0 at dwctwo0: USB revision 2.0 scsibus0 at sdmmc0: 2 targets, initiator 0 sd0 at scsibus0 targ 1 lun 0: <SD/MMC, SL32G, 0080> removable sd0: 30436MB, 512 bytes/sector, 62333952 sectors uhub0 at usb0 configuration 1 interface 0 "Broadcom DWC2 root hub" rev 2.00/1.00 addr 1 uhub1 at uhub0 port 1 configuration 1 interface 0 "Standard Microsystems product 0x2514" rev 2.00/b.b3 addr 2 uhub2 at uhub1 port 1 configuration 1 interface 0 "Standard Microsystems product 0x2514" rev 2.00/b.b3 addr 3 uvideo0 at uhub2 port 2 configuration 1 interface 0 "Logitech HD Pro Webcam C920" rev 2.00/0.11 addr 4 video0 at uvideo0 uaudio0 at uhub2 port 2 configuration 1 interface 3 "Logitech HD Pro Webcam C920" rev 2.00/0.11 addr 4 uaudio0: class v1, high-speed, sync, channels: 0 play, 2 rec, 2 ctls audio0 at uaudio0 axe0 at uhub1 port 3 configuration 1 interface 0 "ASIX Elec.

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.

Re: Raspberry Pi 3B+ panic on changing video0 permissions for motion

Can you try a beefier power supply?
I've had weird crashes on a RPi3 with a logitech video camera whenever I tried to take pictures (using fswebcam). I replaced the power supply with one that could deliver more Amps, and the crashes were gone. (this is some time ago by now, haven't used that setup recently). This may very well be a red herring, but it's good to rule out. Note I never used this motion package.

Exactly the same way. Checkout src/sys (no need for all of src if you're only building a kernel), cd /sys/arch/arm64/compile/GENERIC or GENERIC.MP, make obj, make config, make, doas make install > I'm assuming I would need something more high-powered > than the Pi to build.

So yes there would be no problem building on a Pinebook Pro if you have one available. (Or Raspberry Pi 4 which is pretty quick). Same for userland software / packages / etc. There's not a general problem building on RPi3 either though (I have to say I'm surprised you've got this much running on 3B+ already, I thought the USB controller driver was in worse shape than this). |

Thanks, just started checkout on the 3B+ and will also try on the Pi4 and Pinebook Pro. The axe0 usb-to-ethernet let me get the urtwn firmware for the TP-link USB wireless TL-WN823N, which seems to work perfectly. |

Insufficient info makes it difficult to find and fix bugs. Hmm, I was trying to sync this function with the NetBSD code, but it looks like the gap between them is too large. Since I can't test this myself here I'm afraid I can't help much with that, sorry. |

I'm happy I could install OpenBSD on the Pi, get wireless working, and even compile a kernel. I might try to get the camera to work on a Pinebook or Pi 4or look into attaching an IP camera and see what happens. It was also suggested that a better power supply might help, and I'll try that when it arrives. Thanks! |

I doubt that this has something to do with powering. Obviously something goes wrong with dwctwo(4) ISOC frames accounting ... I guess there are not so many testers for this driver who try ISOC devices :-) |
