At some point I unplugged the phone. I let the computer sit for an hour to see if anything would happen; the GUI continued to be displayed, and it continued to be unresponsive to all keyboard and mouse input. My phone tends to have a poor and inconsistent USB connection. While that's a problem, it shouldn't be the kind of problem that leads to a system crash. I plug this phone in regularly using the same cable, and this is the only time it caused a crash. It usually connects via MTP without problems. It is conceivable that some other application caused the crash, or reduced the available memory enough to expose a bug in usbfs. However, the 640,442 error messages in /var/log/kern.log makes me think this is a usbfs problem. I'm not sure where to report this bug, as the logs indicate it is related to usbfs, which this says has long-since been deprecated and removed from Linux: https://askubuntu.com/a/388062 ## LOGS $ grep 'did not claim interface' /var/log/kern.log | wc -l 640442 $ grep 'did not claim interface' /var/log/kern.log -B15 | head -n30 Apr 18 15:45:00 Lenovo-G550 kernel: [230782.257893] IPv6: ADDRCONF(NETDEV_UP): wlp4s0: link is not ready Apr 18 15:45:02 Lenovo-G550 kernel: [230783.535686] IPv6: ADDRCONF(NETDEV_CHANGE): wlp4s0: link becomes ready Apr 18 17:33:17 Lenovo-G550 kernel: [237280.152047] usb 2-1: new high-speed USB device number 35 using ehci-pci Apr 18 17:33:17 Lenovo-G550 kernel: [237280.310148] usb 2-1: New USB device found, idVendor=22b8, idProduct=2e82 Apr 18 17:33:17 Lenovo-G550 kernel: [237280.310152] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Apr 18 17:33:17 Lenovo-G550 kernel: [237280.310154] usb 2-1: Product: XT1031 Apr 18 17:33:17 Lenovo-G550 kernel: [237280.310156] usb 2-1: Manufacturer: motorola Apr 18 17:33:17 Lenovo-G550 kernel: [237280.310158] usb 2-1: SerialNumber: TA9750117R Apr 18 17:33:19 Lenovo-G550 kernel: [237281.560368] usb 2-1: USB disconnect, device number 35 Apr 18 17:33:19 Lenovo-G550 kernel: [237282.016043] usb 2-1: new high-speed USB device number 36 using ehci-pci Apr 18 17:33:19 Lenovo-G550 kernel: [237282.173616] usb 2-1: New USB device found, idVendor=22b8, idProduct=2e82 Apr 18 17:33:19 Lenovo-G550 kernel: [237282.173620] usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 Apr 18 17:33:19 Lenovo-G550 kernel: [237282.173622] usb 2-1: Product: XT1031 Apr 18 17:33:19 Lenovo-G550 kernel: [237282.173624] usb 2-1: Manufacturer: motorola Apr 18 17:33:19 Lenovo-G550 kernel: [237282.173626] usb 2-1: SerialNumber: TA9750117R Apr 18 17:33:34 Lenovo-G550 kernel: [237297.211272] usb 2-1: usbfs: process 31829 (pool) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.344058] usb 2-1: reset high-speed USB device number 36 using ehci-pci Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501039] usb 2-1: usbfs: process 31829 (pool) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501220] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501228] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501233] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501238] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501243] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501248] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501254] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501259] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501264] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501277] usb 2-1: usbfs: process 31824 (events) did not claim interface 0 before use Apr 18 17:33:35 Lenovo-G550 kernel: [237297.501283] usb 2-1: usbfs: process
