The PC freezes completely when I try to shutdown directly from Gnome interface. This happens specifically after I do updates (emerge -uDN world). I cannot figure out what is causing the problem, since a few seconds after I press the shutdown button the system freezes (still in the Gnome interface) and after I restart there is nothing in the logs. But here are some interesting pointers. 1. The problem only happens if I try to shutdown directly from Gnome interface. 2. It does NOT freeze if I enter Gnome from the console (i.e. run "startx"), do my updates (emerge -uDN world), logout from Gnome and then shutdown from the console. 3. However it DOES freeze if I enter Gnome from the console (i.e. run "startx"), do my updates (emerge -uDN world), and from Gnome interface press shutdown button. Help on how to trace this problem with be much appreciated.

Does the problem happen if instead of startx, you start gnome from a login manager (e.g. gdm)? Do you have portage-related processes still running after emerge finishes? (Check using "ps -aux" or pstree or similar)
Here are the answers for the questions posed by Alexandre: # Does the problem happen if instead of startx, you start gnome from a login manager (e.g. gdm)? Yes, that how I used to login the machine, and when I noticed it starting happening. # Do you have portage-related processes still running after emerge finishes? (Check using "ps -aux" or pstree or similar) The emerge processes are definitely stopped.
Created attachment 409972 [details] Photo of call trace I was able to take picture of call trace of one instance of a freeze. Not sure if it helps.
Maybe kernel people will know about how to debug that traces :/
