That kernel version introduces multi queue block i/o for virtio_blk, which in turn does not any more call blk_init_queue() but blk_mq_init_queue() instead. Dracut matches against symbol blk_init_queue but not yet against symbol blk_mq_init_queue. This should be fixed for Fedora and also for all RHEL derivatives ... In the mean time there is this WORKAROUND: 1) check if virtio_blk is in intrd: # for i in /boot/initramfs-* ; do echo $i: ; lsinitrd $i | grep virt ; done 2) if virtio_blk is missing in the relevant initrd, then # echo 'add_drivers+="virtio_blk"' >/etc/dracut.conf.d/force-vitio_blk-to-ensure-boot.conf (NOTE that the .conf extension is mandatory !) 3) then rebuild the initrd -- You are receiving this mail because: You are the assignee for the bug.
