Early boot became slower

Hi all,

since linux-image-4.8.0-2-amd64 the early phase of my booting process
became slower (~10 secs). I think that it has to do with the
framebuffer. This is the only relevant difference in dmesg:

4.8.0-1-amd64:
simple-framebuffer simple-framebuffer.0: framebuffer at 0xe0000000, 0x7e9000 bytes, mapped to 0xffffc1e201000000
simple-framebuffer simple-framebuffer.0: format=x8r8g8b8, mode=1920x1080x32, linelength=7680
simple-framebuffer simple-framebuffer.0: fb0: simplefb registered!
fb: switching to radeondrmfb from simple

4.9.0-1-amd64:
vesafb: framebuffer at 0xe0000000, mapped to 0xffffb23701800000, using 8128k, total 8128k
vesafb: mode is 1920x1080x32, linelength=7680, pages=0
vesafb: scrolling: redraw
vesafb: Truecolor: size=0:8:8:8, shift=0:16:8:0
fb: switching to radeondrmfb from VESA VGA

I see that CONFIG_FB_SIMPLE is not set anymore. Is that a reason for
that? Any way to fix this without recompiling?


Thanks in advance,
Mattia
