boot not possible after upgrade fom Kernel 4.9.0 to Kernel 4.9.3

Hello all,

after a upgrade from Kernel 4.9.0-2 to Kernel 4.9.3-1 it isn’t possible to boot the machine. Symptom is the following: at the konsole (e.g. tty1) it isn’t possible to do an input, it seems to be restarting over and over again.

Here a snippet from the journalctl logging:

The only possibility to come to a running system is to fall back on the installation with teh previous kernel.

Any help is appreciated

Leap 42.2 or Tumbleweed or …?

32 or 64bit?

Apparently, Tumbleweed, according to the thread title:

Post a reply to the thread: TUMBLEWEED boot not possible after upgrade fom Kernel 4.9.0 to Kernel 4.9.3
lol!

Hi, there are a couple of issues concerning booting with 4.9.x kernels whose fixes are in the pipeline and should land possibly in 4.9.6.
See these bug reports for details; https://bugzilla.kernel.org/show_bug.cgi?id=191121 https://bugzilla.suse.com/show_bug.cgi?id=1017783
Feel free to file a new bug report if you think your problem is different.
Or stick with 4.9.0 for the time being and wait for the fixes…

hi,

fwiw

updated to kernel 4.9.4 this morning on Tumbleweed 32bit os

needed to do a cold boot then all found to be ok

cheers

So I am running Tumbleweed on a 64 bit system:
(by hxtools sysinfo) [willnixWlan] openSUSE Tumbleweed 20170123 | Linux 4.9.0-2-default x86_64 | 4-thr Intel(R) Core™ i5-4460 CPU 3400MHz | Load: 0.26 Tasks: 641 | Mem: 1608/3896MB | Disk: 63/3794GB | Gfx: NVIDIA Corporation GM107 [GeForce GTX 750 Ti] @ 1280x1024

Yesterday I tried to run the system with Kernel 4.9.3 after a cold boot, but no success :frowning:

Today Kernel Version 4.9.6-1 was available, so I gave it a try. Unfortunately without success.

My current workaround:

  1. boot in init level 3
  2. login as root
  3. xinit
  4. su - myusername
  5. export DISPLAY=:0
  6. startkde

No Radeon graphics, see komment #6

I am having a similar problem. I just upgraded from SUSE 13.2 to Tumbleweed and it boots to the command line as follows:

   4.00281] sp5100_tco: I/O address 0x0cd6 already in use

Welcome to openSUSE Tumbleweed 20170203 - kernel 4.9.6-1-default (tty1).

Is this a graphics card problem?

AMD driver? Probably what driver where you using? The fglrx it should be removed the AMD drivers have changed and now are AMDGPU and proprietary AMDGPU-PRO the old fglrx driver is dead and won’t work in newer kernels

Hi, I’m a newbie, but I think I had a similar problem, albeit, with a different graphics card.

You mention you are using Nvidia Geforce, are you using the nouveau driver or the nvidia one? Perhaps the problem lies there.

sddm seems to be acting up? Could it be so?

Please Gentlemen, the OP describes an Intel+Nvidia laptop, possibly an Optimus one in this thread: don’t mess up this thread with different issues and open your own thread describing your configuration in detail.
Thanks.

To the OP:
Can you boot to console (press “E” at the GRUB menu screen, look for a line beginning with “linuxefi” and append “3” without quotes, then press F10 to boot)?
If so, can you look at /var/log/Xorg.0.log for clues about what went wrong?
Is the Nvidia driver built and installed?
If not so, can you remove the nouveau driver from the blacklist and boot with that?
Does the workaround suggested in post #10 work?

Problem solved:

  1. Xorg-Repository added: http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_Tumbleweed
  2. zypper dup

All works fine. :slight_smile:

Congratulations, an X server problem then? What packages were actually upgraded during this last zypper dup?

Yes, quite an X server problem.

In the end, I’ve reinstalled the entire system based on the current Tumbleweed Network Install CD. The same problem. But now without working workaround.
So I’ve tryed the xorg repository.

These are the installed packages (according zypp history file):

Maybe the newest sddm in the last few snapshots needs the newer xdm or xorg-x11-server that are available in the X11:/XOrg repo?
From your post #10 it seems related…

As a comparison, I’m running two Leap 42.2 Gnome instances (gdm, NOT sddm as display manager) here without problems, with the following packages:
#1 “default” repos


kernel-default         | package | 4.9.5-2.1.g9bb1a8a
xdm                    | package | 1.1.11-13.1
xorg-x11-server        | package | 7.6_1.18.3-7.1

#2 X11:/XOrg repo enabled


kernel-default         | package | 4.9.8-1.1.gaf90696
xdm                    | package | 1.1.11-201.1
xorg-x11-server        | package | 1.19.1-479.2

Both had problems booting with the 4.9.0 kernel but have been OK as soon as bpetkov published the patch that eventually landed in 4.9.4.
So maybe what we are dealing in this thread might NOT be related to the kernel and might be a display manager / Xserver issue…

:slight_smile: Problem is now solved.
I installed the kernel-default-4.9.8-1.1.x86_64 and the NVIDIA Driver NVIDIA-Linux-x86_64-378.09
With this combination everything works fine again.
