Kernel 4.4.1-1 fails to boot - root volume “does not exist” - 3.10.0.327 and 4.3.3-1 both continue to boot fine

I'm trying to install and boot kernel-ml (currently 4.4.1-1) on RHEL 7.2 following the instructions here: http://linuxg.net/install-kernel-4-x...-7-and-rhel-7/

Install works fine and on reboot I can choose the new kernel from the grub menu - however it fails midway through booting up.

When it fails, I can see multiple instances of the following:

Code:
dracut-initqueue[632]: Warning: dracut-initqueue timeout - starting timeout scripts
Followed by this:

Code:
dracut-initqueue[632]: Warning: Could not boot.
dracut-initqueue[632]: Warning: /dev/mapper/vg_root-lv_root does not exist
dracut-initqueue[632]: Warning: /dev/vg_root/lv_root does not exist
Starting Dracut emergency shell...
I can still boot into the previously working old kernel, and to another 4.x (4.3.3-1) without issue, but 4.4.1-1 fails at this point every time. SO far I've tried the following with no success (some of the iseda come from http://askubuntu.com/questions/56773...t-doesnt-exist which looked like a similar error):
  • Exiting the dracut emergency shell - boot does not progress any further
  • Specifying root volume by UUID in the grub config - still not found
  • Checking if lvm2 is installed - it is
  • ls /dev/mapper - all I see under here is "control"
  • Added all_generic_ide boot parameter - no change
  • Rebuilt the initramfs for the broken kernel - no change
  • Removed rhgb and quiet from boot params
  • listing disks with lvm pvdisplay / lvm lvdisplay / lvm vgdisplay - none found, blank output

I'm not sure what else I can try here or what to do next - not overly familiar with the boot process at all so I'm already out of my depth - any pointers appreciated

That looks like broken initramfs, but you state you rebuilt it. How ?.
Do you have any crypto involved ?.
Do you get a /run/initramfs/rdsosreport.txt created when you are drooped into the dracut shell ?. Have a look in there for any hints.

To rebuild initramfs I used the following:
Code:
dracut --kver 4.4.1-1.el7.elrepo.x86_64 --force
Command completed successfully etc but no change in the boot error.

No crypto involved here.

Yes I have a /run/initramfs/rdsosreport.txt generated - unfortunately I've nowhere to copy it to etc so I can't upload it. I've had a look through it for errors etc and the only thing jumping out me is thw following round the time it fails:

Code:
systemd[1]: Received SIGRTMIN+21 from PID 632 (plymouthd)
Anything specific I should be looking for in here?

I have updated my OS from Linux 7.1 (kernel 123) to Linux 7.2 (kernel 327) and have the same issue. As solution, i've boot from the old kernel and it's help. Has anyone a solution?

In my case the problem wad in /etc/lvm/lvm.conf
After update Linux parameter filter became a new value: /sd* devices was black-listed.
I disabled the filter parameter by commenting the string and rebuild the boot image like this
dracut -f -v /boot/name.img name
It helps me.

I resolved the issue.
The problem was in /etc/lvm/lvm.conf file and filter-parameter string.
After updating a kernel the parameter became a new value like this /sd*
I disabled the filter parameter by commenting the whole string with the filter parameter and rebuild a boot image like this
dracut -f -v /boot/initramfs-3.8.13-118.3.2.el7uek.x86_64.img 3.8.13-118.3.2.el7uek.x86_64
It helps me
