You have been subscribed to a public bug: On kernel 4.10 from the linux-hwe-edge package, I'm experiencing frequent freezes on my surface pro 3. This starts mostly when using firefox, where first firefox freezes (window is becoming grey). When I don't close firefox immediately (killing it, as its window greyed out), the complete system kinda locks up. When I kill it, its process is still as defunct visible in the process list, and I can't start a new instance of firefox.
When I don't kill it, the NMI watchdog BUG occurs shortly after and I have to shut down the system via power button. It's not completely dead, as I can still ping the device and when I'm ssh'd into it, the shell is not completely dead. I'm having a tail -f /var/log/syslog open via ssh, as I can't look into it anymore when the desktop environment locked up. Here I can close the tail -f command, but can't start any new processes. This did not happen with the linux-signed-image-generic-hwe-16.04 (4.8.0.51.22) yet. apt-cache policy linux-image-generic-hwe-16.04-edge: 4.10.0.20.13 lsb_release -rd: Ubuntu 16.04.2 LTS I attached the excerpt of /var/log/syslog.
