I've tried this on multiple exact server configs: Dell R610, iDRAC 6, Same firmware. Always worked installing Centos 6 and 7 on the same boxes with no issues. I tried iDRAC reset. I even power cycled the IPMI switches as well.
Every time I try to install Centos it literally hangs on 143MB, each time, each box. I tried a fresh downloaded iso too. Same thing. I'm absolutely baffled. I'm in Mexico now so wifi is a bit slow, but I left it overnight and still stuck at 143MB. Same issue at 2 different hotels to top it off.
