Created attachment 1452866 [details] This is the dracut SOS report file Description of problem: when rebooting either with 4.16.5-300 or 4.16.15-300, the boot gets about 15 seconds in, goes very quiet, then puts up a dracut timeout warning after about a further 140s. Eventually it drops to the dracut shell with the warnings Warning: /dev/VolGroup01/LogVol00 does not exist Warning: /dev/VolGroup01/LogVol01 does not exist Warning: /dev/mapper/VolGroup01-LogVol01 does not exist I can boot happily under the remaining old F26 kernel, 4.15.17-200. Version-Release number of selected component (if applicable): How reproducible: for me, very. Steps to Reproduce: 1. reboot 2. don't select old F26 kernel at grub menu 3. Actual results: system fails to boot, drops to dracut shell Expected results: system should boot Additional info: dracut recommended I save a copy of the rdsosreport.txt file, which is attached.
Please check, if your MD_UUID / rd.md.uuid is valid. We had some reports about the MD_UUID changing. What is the output of: # dracut --print-cmdline # for i in /dev/md*; do mdadm -D --export $i; done | grep MD_UUID

What's lvm2 version? This looks like yet another duplicate of Bug 1575762. Do you still see the problem after update of lvm2 to lvm2-2.02.177-5.fc28 and regenerating initramfs using `dracut -f` ?
It was indeed lvm2-2.02.177-4.fc28. Having updated that package, brought the kernel up-to-patch, and regenerated the appropriate file with `dracut -f --kver 4.17.3-200-fc28.x86_64` my system has now happily booted into 4.17.3-200.fc28, so I guess you are right, and this is a duplicate of the referenced bug, and can be closed as such. I apologise for not having found the other bug when searching before logging this one.
Thanks for verifying it *** This bug has been marked as a duplicate of bug 1575762 ***
