Package: src:linux Version: 4.8.15-2 Severity: normal Dear Maintainer, I plugged in a USB webcam, device ID 046d:0990 into my Thinkpad X220. The kernel froze with a NULL pointer dereference. here's the full log. I had to shut the machine down hard and restart it. Later, i rebooted into 4.9.0-1-amd64 (version 4.9.2-2) and tried the device again, with different errors, which i'll follow up with in another bug report. her's the NULL pointer dereference: Jan 26
