Cannot boot into Fedora 25 while upgrading to 26

asked 2017-07-11 12:34:57 -0500

Hello guys, I make myself into deep trouble.

I have installed Fedora 25 and a few hours ago I upgraded to 26 by following the instructions provided by Fedora magazine:

However when I first rebooted the systemd showed an error message like "cannot get freq at ep 0x...". I thought my system would hang so I rebooted my PC again. After that, every time I try to boot into the Fedora 25 kernel and all I get is just a screen with 3 white square bubbles, and the screen stops just right there.

Now I have a Fedora 25 netinstall CD and a 26 Live DVD. Where do I start to rescue my Fedora? Thank you guys for any help.

When you see those three white dots, press ESC, you'll see startup log and should find out what's currently happening.

Which steps of upgrade process have you successfully completed? "$ sudo dnf system-upgrade reboot" was interrupted by you manually resetting computer, right?

Pressed ESC and within a few minutes the screen shows nothing. I did every steps including "sudo dnf system-upgrade reboot", and ya, that reboot was interrupted by me resetting the computer.

Have you tried booting to a CLI? It's possible that whatever is hanging is only needed for a GUI.

cannot get freq at ep 0x..seems to be related to the audio subsystem (usb sound card a/o speakers?). On grub menu list hit e for modyfing kernel command line, find and delete rhgb and quiet and boot with Ctrl-X. You should be able to see all booting messages. Anyway if you have a separate /home partition my suggestion for a quick fix would be to reinstall Fedora.

Tried booting into boot level 3 with the method provided by fcomida, and I got this: [4.782720] systemd - journald[358]: Received SIGTERM from PID 1 (systemd)[4.792293] systemd: 17 output lines suppressed due to ratelimiting And the screen hangs since that. Fortunately I did have a separate /home partition, but I just don't want to give up and install F26 directly on the old / and /boot partitions yet.
