I upgraded my PhenomX4 machien from 11.3 hoping that it would fix the kernel crashes I am having.
This morning was first use since upgrade via DVD. I have been logged out three times without provocation or warning, and just now the machine went catatonic, just flashing the caplock and scrolllock lights. Still rebooting so have not managed to look at the logs if any.
In case it matters this is running plain X with fvwm; no Gnome or KDE, No desktop
I am beginning to suspect 11.4 is not ready for deployment.
