Revised report: 4.4.0-83-generic only affected one out of three Dell Precision M4600s. A quick look at their device compliment didn't reveal anything obvious. That is, the afflicted machine has the same network adapter as the other two, and the same camera device of one of the other two, and nothing unique on the USB bus.
Also, 4.4.0-87-generic seems to have fixed the problems in the affected machine. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1703091 Title: Kernel panic - not syncing: Fatal exception in interrupt Status in linux package in Ubuntu: Confirmed Bug description: I have a Clevo P150SM laptop. Recently, I have frequent kernel panics "Fatal exception in interrupt". Screenshot at https://i.stack.imgur.com/eZRcu.jpg (I will try to upload the screenshot of the console once I have a bug number). It happened the 1st time kernel 4.4.0-83 was installed and since yesterday's package updates was happening almost all the time. Today (the next morning) kernel 4.4.0-83 is booting fine. The symptons are simular to bug 1702164 (Sometimes it gets far enough to boot the X11 interface - and then crashes, Sometimes it crashes while still in console text mode). 2 leds are blinking: "CapsLock", and the other led which is not NumLock (but I don't know what it is). NumLock is not blinking. I alread did as root: apt clean apt install --reinstall linux-image-generic linux-image-4.4.0-83-generic update-initramfs -u -k 4.4.0-83-generic reboot but it stays the same. (The first time I upgraded to kernel 4.4.0-83 the power went down in the middle of the upgrade, and I fixed the problem more-or-less with the commands above.). When it crashes, I manage to boot in 4.4.0-81-generic, and it still seems to work fine.
