Installed 5.0 kernel, broke my OS.

Hi all,

The other day I ran dnf update and the kernel was upgraded to 5.0. All was fine until I decided to reboot. As long as I'm trying to boot the 5.0 kernel, it gets to a certain point and then the screen flashes intermittently between off and on (but black).

Never having encountered this before, the only thing I could think to do was go into rescue mode (which booted to terminal instead of the usual GUI) and look at journalctl. A few things popped out:

1) nouveau 0000:01:00.0: DRM: Pointer to TDMS table invalid
2) systemd[1]: Timed out waiting for device dev-mapper-fedora\x2swap.device
3) /etc/multipath.conf does not exist, blacklisting all files. You can run "/sbin/mpathconf --enable" to create /etc/multipath.conf. See man mpathconf(8) for more details.
4) boot-efi.mount: Mount process exited, code = exited status = 32.
5) boot-efi.mount: Failed with result 'exit-code'
6) Failed to mount /boot/efi.

I did run the /sbin/mpathconf --enable command and navigated to /boot/efi but didn't see anything in there. That might be a rescue mode thing versus a different kernel thing, as in 4.20 I do have files in there at the moment.

Hopefully this is enough information... what do I need to do to fix this? I remember something more about a missing vfat something but I can't conjure the details. I'm still fairly new to linux as a whole.


Thanks in advance!

I'm seeing this exact same problem on my Dell XPS 15 9570. Except, I've already had the nouveau driver disabled for some time.

I've filed a bug for my similar issue here.

It would be great if you could update the bug with your info and log file.

1) could be a regression in nouveau, the open source nvidia driver - you can try booting with parameter nomodeset to see if it helps but graphics might be limited (slow)

2) Hard to say, need more information to find out why it times out; what happens if you do lsblk and sudo swapon /dev/mapper/fedora-swap

3) can be ignored

4, 5, 6) suggests the EFI system partition is corrupt, use sudo blkid to find the EFI system partition, and then sudo dosfsck -av /dev/ The thing is, /etc/fstab should have an entry for /boot/efi with the last column being 2 so it should have already tried to run dosfsck, and maybe it can't be repaired.

Sure can.

1) Right now I'm editing GRUB to use nouveau.modeset=0 and that seems to be helping -- if I don't do anything at all, even my working instance freezes after logging in. I'll try nomodeset and see what happens.

So--I tried posting the output of lsblk and I get a "content forbidden" error. When I run the swapon comand, it says it failed: Device or resource busy.

blkid shows my EFI sys partition on nvme0n1p1, which is "vfat" type. I then ran the dosfsck -av command and got fsck.fat 4.1 (2017-01-24( open: Is a directory. <-- is that the expected output?

I'll run all these in rescue mode as well to see what (if anything) changes. EDIT: Nothing changes.

Try booting with 4.20 kernel and run: dracut -f <imagename> <kernel version>. Look at /boot for <imagename> and <kernel version=""> for kernel 5.0. Probably a dnf reinstall for latest kernel would do as well.

Is it related to what fixes?

I guess so, indeed initramfs is corrupted in his system.
