Subject: Re: current mainline doesn't boot

Interesting to see that Fedora has similar problems with current
kernel (I pulled mainline again a few hours ago).

Fedora 20 x86_64 in vmware boots to logon prompt but no mouse, no
keyboard, system hung.  Ctl-alt-f1 doesn't do anything.  Even with
verbose on kernel boot line, the extra debug messages have all been
cleared by the time the hang occurs so nothing useful displayed.

To be as safe as possible I used their default .config
/boot/config-3.16.6-200.fc20.x86_64 to do a clean build of mainline.
Once again, 3.16 and 3.17 work but not current mainline.
