I'm getting a panic when trying to use fswebcam to grab an image from my webcam on a Raspberry Pi 3:
panic: kernel diagnostic assertion "xfertype != UE_ISOCHRONOUS || xfer->nframes < DWC2_MAXISOCPACKETS" failed: file "/usr/src/sys/dev/usb/dwc2/dwc2.c", line 1306 Stopped at panic+0x158: TID PID UID PRFLAGS PFLAGS CPU COMMAND *502853 41556 0 0x3 0 0 fswebcam db_enter() at panic+0x154 panic() at dwc2_device_start+0x45c dwc2_device_start() at usbd_transfer+0x140 usbd_transfer() at uvideo_vs_start_isoc+0x78 uvideo_vs_start_isoc() at uvideo_streamon+0xb0 uvideo_streamon() at VOP_IOCTL+0x3c VOP_IOCTL() at vn_ioctl+0x70 https://www.openbsd.org/ddb.html describes the minimum info required in bug reports. Insufficient info makes it difficult to find and fix bugs. ddb> Unfortunately, I seem to be having some issues with my serial console cable, as I can't type on the console anymore (I still get output, but it doesn't take input). I'll try to get that sorted and report with more details.
