Today I issued an apt-get dist-upgrade and the kernel has been upgraded to the above.
I always had this issue but only when getting back from hibernation (I've installed only a couple of months ago) After the upgrade of today the issues become severe.. I cannot have a coffee without rebooting afterwards :) Today only I've seen the panic message on the console and more logging about nouveau I'm going to try 4.1-rc8-unstable from kernel-ppa/mainline and report back from here http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.1-rc8-unstable/linux-headers-4.1.0-040100rc8-generic_4.1.0-040100rc8.201506150335_amd64.deb Thank you Best Luca 2015-06-15 20:49 GMT+02:00 Joseph Salisbury <joseph.salisb...@canonical.com> : > Did this issue start happening after an update/upgrade?
