I thought I would try a 11.3 live CD on my new Asus P7P55D-E i7 machine. The boot up process froze and in the process caused my onboard network adapter to freeze to the point where I had to remove power from the system completely, rebooting was not enough. This caused me some moments of serious concern since that event some time ago where Intel bits where getting there firmware cooked by errant processes. I went out mowed the lawn and turned it back on. It worked.
Still something is very wrong here for it to get so far, my 11.2 live disk worked OK IRC.
