Hi Andy,

I'm not shure I understood this alright. I can't really debug this,
since I have no access to the machine. 
Fact is the machine rebootet instantly after firing up the Desktop
Environment and putting radeon.dpm=0 "fixed" it. This happened after
upgrading the distribution via some gui mechanism ( which is what my
mom did).

So, IMO, in order to make ubuntu usable on those machines, this should
be the default. If there is a known real fix for this hardware, maybe
this could be backported, but i don't know of any.

Would it help, if I tried to get the hardware specs, so that you know
which radeon supported chipset this happens on? But of course this
wouldn't preclude it from happening on other similar chipsets...
is there some simple way to gather the needed information from the

Best regards,
