My (pretty new) computer boots very slow; I see the purple empty screen for more than a minute until the Ubuntu logo appears.
dmesg shows a gap of 60 seconds in which nothing seems to happen (no CPU load or iowait). I suspect is has something to do with
udevadm, since disk utilization spikes when they exit.
I already unplugged everything I could (second harddrive, all usb devices), but that didn't help.
Setting udev logging to "debug" in
/etc/udev/udev.conf gave me some logs, but without timing information.
What can I do to debug this further?
