On my Dell Inspiron 3520 with F19 Alpha RC2 installed and booting with EFI, grub2 hangs when loading the initramfs 95% of the time. Occasionally it will boot, but most of the time I have to power cycle manually and select refind from Dell's EFI boot selector and use that to boot Fedora. I experience this with both the kernel included with RC2 (kernel-3.9.0-0.rc4.git0.1.fc19.x86_64) and the latest kernel in updates-testing (kernel-3.9.0-0.rc6.git0.1.fc19.x86_64). Let me know if there's anything I can do to debug this. Thanks!
