Let me announce the 3rd piece of broken hardware in 3 months. This is definitely too much :( First my Dreambox 7025, then a Denon AV receiver, and now my Linux workstation decided to die. It looks like (hopefully) just the PSU is to blame though -- doesn't react to incoming power any more.
As if I had time for such things *sigh* ...
Update: It looks like there was a power surge during a thunderstorm. My Dreambox and AppleTV halted as well... aaargh
Update 2: A new PSU brings the workstation back to live *phew*. Dreambox and AppleTV did not have permanent damages either.
