[Bug 592780] Re: [Lucid] kernel suspend + resume works only once, 2nd timesystem freezes

[ingo]

So, at least I found the root cause: the damned USB-subsystem!

Here I describe what I did and finally found how to confirm that:

Boot Lucid with the kernel parameter "nousb"
(unfortunately my mouse is USB-type, while keyboard is PS/2. So I had to perform these steps)
cange to a console (Ctrl+Alt+F1)
type "echo mem > /sys/power/state" -> system goes to standby
resume by tipping power button results in scrambled console, so
change to x-server screen (Ctrl+Alt+F7) with no mouse here of course
change back to console 1 (Ctrl+Alt+F1) and all is fine!

This you can repeat as often as you like which proves that without USB-
subsystem enabled suspend works fine!

Tomorrow I will try with an old PS/2 mouse from graphical screen
(x-server) - I'm sure it will work as well.
