Hello,
I've just installed F19 x86_64 from DVD.
The first issue is that the GRUB boot screen
* is only text-based (white text with a black background),
* and uses an inadequate text encoding since it shows question marks in place of the umlauted "o" (i.e., the o vowel with two dots on top of it) in the Schrodinger word
The second issue is related to plymouth.
The service plymouth-quit-wait is marked as failed:
plymouth-quit-wait.service - Wait for Plymouth Boot Screen to Quit
Loaded: loaded (/usr/lib/systemd/system/plymouth-quit-wait.service; disabled)
Active: failed (Result: timeout) since Sun 2013-07-07 12:55:22 CEST; 5h 30min ago
