The line below has appeared repeatedly in the logs earlier: Feb 5 23:02:02 a1 wdm: Cannot read randomFile "/dev/mem", errno = 14 This happens when wdm starts so I'm going to guess it uses it for something funny, "randomFile" it calls it?? With the WARN_ON check added and booting 3.8-rc6, it would choke wdm somehow and it wouldn't start properly so that even the error out above doesn't happen.
