pstore: Unknown compression: deflate - after kernel upgrade

Post by odelgado » 2020/02/03 10:50:51

Hi there!

I've installed the following OS:

Code: Select all

[root@master-node ~]# hostnamectl
   Static hostname: master-node
         Icon name: computer-server
           Chassis: server
        Machine ID: 8b84d89f05a14a01a1ff01c3c1c5f678
           Boot ID: 95a53426df874cce83102de232d60f53
  Operating System: CentOS Linux 7 (Core)
       CPE OS Name: cpe:/o:centos:centos:7
            Kernel: Linux 5.5.1-1.el7.elrepo.x86_64
      Architecture: x86-64
[root@master-node ~]#
I've upgraded to this Kernel: Linux 5.5.1-1.el7.elrepo.x86_64 from 3.10.0-1062.9.1.el7.x86_64. Now, when we boot the server, we got the following message through VGA:

pstore: Unknown compression: deflate

So, we cannot login/see GUI to login. I can connect to the server by SSH and I see the following message (I'm not sure if they are releated)

Code: Select all

[root@master-node ~]# abrt-cli list --since 1580475843

The Autoreporting feature is disabled. Please consider enabling it by issuing
'abrt-auto-reporting enabled' as a user with root privileges
[root@master-node ~]#
The question is... How can I revive the GUI interface? If I boot the old kernel, it works fine.

Thanks in advanced!

This is something you need to report to ELRepo as it is their kernel that you are using. Their kernels are specifically not recommended for production use. Is there a specific reason why you are trying to use it rather than the distro suppplied one? Or do you just have a case of versionitis?

The distro kernel is maintained by Red Hat for RHEL and receives regular and (usally) timely security updates. There should be no need to run a more recent one unless you have hardware that is unsupported on it and even then, it's usually better to use one of ELRepo's kmod packages rather than the entire kernel.
The future appears to be RHEL or Debian. I think I'm going Debian.

Thanks for your quickly response. I'm going to report it to ELRepo. I'm trying to install a Kubernetes container and they suggested me to upgrade the kernel because we had a issue. After upgrade the kernel, it works, but we have another issue now...

In any case, thanks for your help. If I find the solution, I will post it here :)

"versionitis" :lol:

Was this ever resolved? I'm seeing the same symptoms: the `pstore: Unknown compression: deflate` error, followed by the GUI not appearing, but the server accessible over ssh.

I'm updating from 3.10.0-1160.25.1.el7.x86_64 to 5.8.5-1.el7.elrepo.x86_64.

Thanks!

And the answer is still the same as it was: you have to ask ELRepo what settings that have compiled with.
