I received out of list the dmesg output from Mohammad

It looks like a hardware error to me:

[   48.729618] iTCO_wdt: unable to reset NO_REBOOT flag, device
disabled by hardware/BIOS
[   48.749361] uvcvideo: Found UVC 1.00 device j5 WebCam JVCU100 (0711:3108)
[   48.751876] uvcvideo: Failed to query (129) UVC probe control : -32
(exp. 26).
