Uncompression error -- system halted

Post by vtwin@cox.net » 2018/03/21 15:46:07

Have an existing CentOS 7.4 system which has been running fine. Was running kernel-3.10.0-693.17.1.el7.x86_64

Updated system today to kernel-3.10.0-693.21.1.el7.x86_64

Upon reboot, I received:

Probing EDD (edd=off to disable)... ok

uncompression error

--system halted.


Everything I've read online seems to indicate some type of corruption on /boot. I rebooted into the 17.1 kernel, I've dismounted /boot and run a fsck on it, as well as badblocks -n -- received no errors at all. I uninstalled and reinstalled the kernel (reboots in-between), error returns. I can take the initramfs image in /boot, and successfully uncompress it with cpio, so it isn't an issue with initramfs.

I can continue to run 17.1 for the moment... but confused as to why I have this issue with 21.1

baffled :?:

Interesting. For background, is this a virtual machine or real hardware? Is there some sort of an exotic CPU or other exotic hardware involved?

When you boot the old kernel, try to regenerate the iniramfs. Most probably something is wrong in it.

Also check the output from rpm -V kernel-3.10.0-693.21.1.el7.x86_64 is blank.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Real hardware, not a virtual machine. A Dell Precision T7610.

32GB

I'm going to perform a reinstall/update. Perhaps something is corrupt somewhere else.

Thanks for all the replies.

Something else must have become corrupt on the root file system at some point, which is either used to build the initial ramdisk or was part of the initial ramdisk's files.

I performed a fresh format/reinstall of 7.4 and upgraded the kernel and the system boots fine.

*shrug*

Almost as bad as Windows :) (ducking)
