Package: systemd-udevd Version: upowerd Severity: normal X-Debbugs-Cc: a.sm...@unb.ca
After plugging a USB-powered light into a USB port (I have used the same light in the same port many times before, but certainly possible that it broke since the last time I used it) the light did not turn on,I get continuous repeated messages in syslog and systemd-udevd is using 100% of the CPU. When I plug the lamp in, I see this: May 2 15:06:59 beta kernel: [18507.692791] usb usb4-port2: over-current condition May 2 15:06:59 beta upowerd[1306]: treating change event as add on

unplugging the lamp, leaving nothing plugged into USB, does not resolve the situation. -- System Information: Debian Release: 11.0 APT prefers unstable APT policy: (500, 'unstable') Architecture:
