F21 Kernel update 3.18.3-201 not booting
I applied the latest kernel update today and now the boot process stalls. I have LVM hosted partitions (apart from boot and efi) and it appears to be having trouble identifying the partitions.
I can reboot in to the previous kernel successfully (3.17.8-300)
I had this problem with kernel 3.18.5, but kernel's 3.18.6, 3.18.7 & 3.18.8 have been fixed.
I applied 3.18.9-200 today and found the issue has reappeared!
However the same work-around works:
sudo -i
dracut --no-hostonly --force /boot/initramfs-3.18.9-200.fc21.x86_64.img 3.18.9-200.fc21.x86_64
Kernels in the 3.19.x range have worked fine. This bug was closed as "not a bug " : https://bugzilla.redhat.com/show_bug....
What log messages do you see during boot?
How far does boot proceed? Do you see Fedora logo (plymouth)? What happens if you press Esc?

Looking at the sosreport - it can't read the two LVM partitions.
It eventually drops to the emergency console, in the meantime the plymouth logo slowly fills.
No binary drivers installed (at this time)
No login - never get far enough through the boot.
It looks like I ...(more)
