Fair enough, I think I found some related files on the HP site, been reading through those.
What I don't understand is this: why is it suddenly a firmware issue now on Ubuntu 12.04, when it wasn't an issue on VMWare ESX? The hardware has not changed. If there's a firmware bug, fine, but why was it handled before and not now? I managed to get an oops out of the current running kernel (3.2.0-40-generic): [69240.280022] INFO: task rs:main Q:Reg:405 blocked for more than 120 seconds.
