Oh I forgot to mention. I've got the USB capture thing and I reproduced the
problem you saw
(with page_alloc failing). The issue was that I forgot to enable these two
kernel optins:
kernel.shmall = 134217728 kernel.shmmax = 134217728
in the sysctl.conf. Once that was set it worked fine. Haven't put the xHCI
controller in box yet
thought.
