Kernel 4.4.0-64-generic freezes on gui

Asked by Axel H.

After updating Ubuntu with apt which includes a kernel update to 4.4.0-64-generic, the system freezes shortly after it boots into the gui. There are no issues booting with kernel 4.4.0-62

It might be caused by WiFi. I have an USB wifi module. When i remove it, Ubuntu with kernel 4.4.0-64 starts without freezing. As soon as I plug it in the system Freezes instantly.

It seems theat I'm not the only one experiencing freezes with this new kernel update. Maybe the security patch is breaking something essential: http://askubuntu.com/questions/886374/ubuntu-16-04-kernel-4-4-0-64-generic-freezes-after-login-screen/886799

Unfortunately Launchpad does not allow to file bugs for Ubuntu directly. It only redirects to wiki page which assumes the OS is still in operational state - major fail.

You should be able to create a bug report for the kernel package via https://bugs.launchpad.net/ubuntu/+source/linux/+filebug?no-redirect
