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
