When you say the browser didn't work, what do you mean exactly?
Do all request just time out?
Do DNS lookups all fail?
Is the GUI just stuck?

The kind of failure is important to finding the cause. I have something
similar - when I copy many large files over wireless to my NFS share
using dolphin, the gui is often stalls and stops responding to mouse
clicks till the copy is done. Firefox is especially affected. I haven't
found what's causing it yet, but it certainly isn't Firefox.

btw, konsole isn't running as root unless you do something like
sudo konsole
from krunner. There's nothing special about a konsole where you became
root. All the gui code that gives it focus and lets it run at all is
still running as user dale. The only privileged process is the bash
running in the terminal

Just remove ohci and uhci from the kernel config


These days all you need is ehci for usb2 and xhci for usb3 (unless you
are using ancient hardware with physical usb1 ports)
