Subject: Re: current mainline doesn't boot

Same thing happened after pulling newly updated mainline kernel
changes a few minutes ago.

Black screen on boot just when you would expect x to be starting.
Hung. Ctl-alt-F1 doesn't do anything.

arch is x86_64.

3.17.1 works.  When I get time I will see if I can figure out more
useful info but this looks like a pretty boring setup:

sfrench@...ntu:~$ glxinfo | grep -i "vendor"
server glx vendor string: SGI
client glx vendor string: Mesa Project and SGI
OpenGL vendor string: VMware, Inc.
sfrench@...ntu:~$ grep LoadModule /var/log/Xorg.0.log
[    18.271] (II) LoadModule: "glx"
[    18.288] (II) LoadModule: "vmware"
[    18.352] (II) LoadModule: "modesetting"
[    18.355] (II) LoadModule: "fbdev"
[    18.360] (II) LoadModule: "vesa"
[    18.369] (II) LoadModule: "fbdevhw"
[    18.372] (II) LoadModule: "fb"
[    18.379] (II) LoadModule: "dri2"
[    18.479] (II) LoadModule: "evdev"
[    18.484] (II) LoadModule: "vmmouse"
