Question - this seems to me not to be a kernel issue (correct me if I'm 
wrong) and thus I'd like to take it to the proper place...
Where should I file this as bug? Is this a hald problem or something more 
complicated?

The swap storm is perfectly reproducible with X/fglrx, compiz and vmware 
workstation running - after resume from suspend2ram it starts. No compiz - 
no problem. No vmware - no problem... Closing vmware -> swapping stops.

If you think this is hopeless since too much closed source software is 
involved, tell me... :-]


Thanks, Andreas
