[PATCH] drm/vmwgfx: Fix passing partly uninitialized drm_mode_fb_cmd2 struct

[Thorsten Leemhuis]

Hi, this is your Linux kernel regression tracker. The relevant code here
is not my area of expertise, nevertheless a few questions:

Maybe I'm missing something, but what made you assume that it's the same
issue? The fix for that issue talked about "garbage" in some structures
that "can cause random failures during the bringup of the fbcon." Yeah,
maybe that ca result in a hang, but I didn't see it that thread (but
maybe I missed)

A bit more details would be helpful. For example: is anything printed at
all before the system hangs? What's the last kernel that worked for you
(and is the newer kernel using a similar build configuration)? Which
graphics adapater did you configure in VirtualBox?

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
