Created attachment 1149476 [details] Fedora 24 nvme install log I've built a new system with a Samsung 950 Pro NVMe SSD as the only storage device attached to a D3417-B11 with an Intel Xeon E3-1225 v5. Trying to install the latest Fedora 24 alpha builds or nightly composes fails, because no `/dev/root` device can be found. dracut-initqueue[694]: /lib/dracut-lib.sh@433(check_finished): for f in '$hookdir/initqueue/finished/*.sh' dracut-initqueue[694]: /lib/dracut-lib.sh@434(check_finished): '[' '/lib/dracut/hooks/initqueue/finished/devexists-\x2fdev\x2froot.sh' = '/lib/dracut/hooks/initqueue/finished/*.sh' ']' dracut-initqueue[694]: /lib/dracut-lib.sh@435(check_finished): '[' -e '/lib/dracut/hooks/initqueue/finished/devexists-\x2fdev\x2froot.sh' ']' dracut-initqueue[694]: /lib/dracut-lib.sh@435(check_finished): .

Complete `rd.debug` log attached. I also tried booting with `root=/dev/nvme0n1`, but that didn't help either. Log in the next commit.
Created attachment 1149478 [details] Fedora 24 nvme install log (root=/dev/nvme0n1)
inst.stage2=hd:LABEL=Fedora-S-dvd-x86_64-24 rd.live.check rd.debug root=/dev/nvme0n1 inst.stage2? and rd.live.check?
anyway, the anaconda part in dracut is searching for a partition/device with LABEL Fedora-S-dvd-x86_64-24 Are you sure, this is available in your system? Reassigning to component anaconda, as this is the installer image
inst.stage2 and rd.live.check were there by default. The latter I assume because I chose the default "Test this media and install Fedora 24" in the grub/syslinux menu. More complete STR on how I came to the above logs: 1. Download a working Fedora 24 Installer image. I used `Fedora-Server-netinst-x86_64-24-20160421.n.0.iso` last time because the openQA results look good. 2. Write the iso to a USB stick. (I was using unetbootin 619-1 from an Arch Linux installation) 3. Boot as UEFI 4. Select "Test this media and install Fedora 24" (optionally add `rd.debug` and remove `quiet`) 5. Boot screen goes until "Starting plymouth" or so and hangs there for ~180 seconds until the dracut timeout scripts run and drops to emergency shell. Checked lsmod and made sure the nvme module is loaded and /dev/nvme0 and /dev/nvme0n1 exist.
adamw strikes again.... https://www.happyassassin.net/2014/02/04/more-on-booting-a-practical-fedora-uefi-guide-and-dont-use-universal-usb-stick-writers/ I'll try this out next time I get to the machine.
(In reply to Johannes Pfrang from comment #4) > 2. Write the iso to a USB stick. (I was using unetbootin 619-1 from an Arch > Linux installation) There's your problem. I don't know exactly what unetbootin does, but it apparently involves modifying filesystem UUIDs (this ISO should show up as 2016-04-21-08-38-11-00 in /dev/by-uuid, it appears to be usb-Generic_Flash_Disk_DFAB1258-0:0 in the log) and labels, and we need those. Writing the iso directly to a USB stick is a better bet.
