dmesg

Booting 3.14.4-200.fc20.x86_64 takes a long time before showing anything. The full dmesg is attached. I think the console is first enabled during


[   13.158912] efifb: probing for efifb
[   13.163970] efifb: framebuffer at 0x90010000, mapped to 0xffffc90016c00000, using 32400k, total 32400k
[   13.163974] efifb: mode is 3840x2160x32, linelength=15360, pages=1
[   13.163975] efifb: scrolling: redraw
[   13.163977] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0
[   13.180470] Console: switching to colour frame buffer device 480x135
[   13.196905] fb0: EFI VGA frame buffer device

Booting faster would be perfect, but just initializing efifb earlier would be awesome.

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 20 kernel bugs.

Fedora 20 has now been rebased to 3.17.2-200.fc20.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 21, and are still experiencing this issue, please change the version to Fedora 21.

If you experience different issues, please open a new bug report for those.

This has been fixed in 3.18:

[    0.856918] efifb: probing for efifb
[    0.856970] efifb: framebuffer at 0x90010000, mapped to 0xffffc90016c00000, using 32400k, total 32400k

[    0.856976] efifb: Truecolor: size=8:8:8:8, shift=24:16:8:0

Not sure what this the status this bug should be set to.
